For the Manual Transmission Drivers...

When in performance mode the only difference between a manual transmission and a DCT is the pumping on the clutch. You still have a direct drive transmission and a gear selector just like any other manual transmission. I don't particularly get any jollies from pumping on a clutch pedal. I could better use the left foot for left foot braking. I am not good enough with the throttle to reliably shift a manual transmission without a clutch so it would be very nice to get rid of the clutch pedal.
I suspect once the car is on the market and everybody finds how much better handling the car is they will jump on the band wagon and buy a DCT. A lot of the unusual shift problems that were encountered with DCTs during street usage have been over come.

Additionally, as cars become stupid fast (i.e., 800hp GT-R's or a stock 720s running 143mph in the 1/4!!!) the DCT becomes more important. If you are bombing a back road or doing a track day in a car like that you really don't miss shifting and rev matching since everything is coming up so fast and you need all of your focus on braking points and turn in. Unless you are Senna and capable of making 2000 shifts a race @ Monaco in a 1000hp turbo MP4/4, haha... but as much as we pretend, we aren't all quite that good at driving. Not to mention the "hot" versions of the C8 will be turbocharged, making the DCT's advantage of no boost loss on shifts even bigger.
However, all of this said, I do hope they make a manual in the C8. I don't believe they will, but they should. Like many people here, 95% of the cars I've owned over the past 20 years have been manual and there is just some unexplainable "fun factor" to rowing gears where you don't actually care if the car is "worse" than a DCT. I sold my LS7 C5Z a few month ago and since then the GT-R has been my only car... I plan to buy a new C7Z Z07/M7 in the spring and CANNOT WAIT to drive a manual again.
I think there is really no "right answer" to this question. For a car enthusiast that loves fast cars and being involved in the experience times are changing very quickly. I do sadly see a point in the near future where the used market will be the only option if you want manual transmission car. I'll enjoy the hell out of these new rocket ships but I can't see a time where I won't have at least one manual car sitting the corner of my garage for those times when I'm in the mood to bang some gears.

There is a little more to driving a manual transmission car then "pumping the clutch pedal" with your left foot.
There is also synchronization of the right foot to control the accelerator pedal, and the synchronization of your right arm/hand to move the shift lever into the right gear, at the right time.

People referencing the CAD drawing as evidence that there won't be a manual should consider that there are likely 2 CAD files, 1 for DCT/Auto and another for manual transmissions.
I won't buy a DCT/Auto Corvette.

Careful what you wish for
Let's assume GM will grant your wish and offer a manual in the ME C8. In order to change the gears an elaborate cable driven shifter would have to be employed since the transaxle sits behind the engine. Would you really enjoy a sloppy shifter and all the headaches that goes with cable adjustments?
A DCT can be driven in manual mode where the driver is in command of gear selection. You will only "miss" the clutch pedal. I have seen too many missed shifts by experienced drivers on the track with a manual. I've never done a fatal 3 to 2 shift (instead of 3 to 4), due to high G's, but have seen the results of one of other drivers. Besides, I doubt you can match the gear change speed of DCT by a manual.
I'm OK with the DCT, my only concern is clutch reliability. Let's embrace progress.

Can you imagine the cost of a totally separate piece of the car's foundation? The tunnel would most likely be designed for a shift lever and then that area blanked off in cars that wouldn't be using it.
Also the top of the tunnel shown in the CAD runs all the way to the firewall with the mounting points for the lower IP support bar, so that portion wouldn't feasibly be interchangeable.

WRT embracing technology, driverless electric cars are on the horizon making both the DCT and the driver obsolete. Once that happens, look for human drivers to be banned from public roads as we will be too unpredictable. Let's embrace progress.
No offence intended. I'm just having fun and illustrating a point.

I agree that's a possibility, but this IS GM after all.. (Paddles on the steering wheel of a manual shift car )

For me, these fast cars are nearly impossible to enjoy on public roads at any sort of 'speed' short of brief bursts, that's why the manual is entertaining. It's mostly when you are going slow that I need that something to make me feel like I'm not in my pickup truck. There is just something fun about pre-selecting, using it to slow down, dropping a gear and manipulating the throttle to hide it cause another hot car is creeping up and you want to be ready, manipulating it for traction (to intentionally lose traction too in tight places), coasting in neutral to hyper-mile, and just generally screwing around.
The track is the one place I think I'd be okay with a DCT, even though I'd still feel more connected in the manual.
I guess if the DCT driven at a high level by say Randy Probst, if the DCT turned out to be like 1.5+ seconds faster around a track, I might have to consider otherwise at that point.
But then Randy was faster at Willow in the manual Camaro than he was in the 10 speed auto so that seems highly unlikely.

I'll grab one of the last C7s or maybe switch over to Porsche. I just can't do an automatic. I need to be "connected" to the car and using both legs and hands is just what feels right to me. I'd even swap over to a Camaro over a ME vette.

Spireland, you know the Camaro is an intriguing package. Outstanding performance, a little back seat action, certainly looks a lot better than a gaudy C7Z, reasonably priced, manual trans, it's got a lot going for it for sure.

OP it sounds like you have made your point of not buying ME "if" it only has DCT without ever having driven one. You can paddle shift a DCT and for some, that is driver involvement. I believe in the driving experience also, but I have driven vehicles with "good" DCT's and they did not disappoint. For many it is not an "either or" situation. I own both manual and auto shift cars and they all serve the purpose for why I bought them. There are some really good DCTs, as well as some manufacturers that didn't do such a good job with them. The same can be said of manual transmissions. Most of us base our opinions on what we have owned or at least driven.......and then there are some that base their opinion on what-ever happens to come to mind. For what it is worth, some manufacturers have dropped their older DCTs for newer automatics.

Why are people comparing paddling through the gears of a DCT on the street with shifting a manual? It's nothing alike as far as experience.

I think the original question is if current manual drivers would buy the ME if only offered with DCT. That means that people will answer with their own experience or feeling as to why or why not. For you or I, it may be nothing like the driving experience in a manual.....but that was not the question. Oh wait....maybe I am not understanding your statement at all. are you talking "driving experience" or the actual "mechanical" experience between the two transmissions? If the driver's experience is what you are talking about; it is sort of impossible for someone to decide what is another person's positive driver's experience.

DCT on track is great... on street it's no better than an auto.

I respectfully disagree...the direct drive connection of the engine to the rear wheels is much more of a direct feel in a dct compared to a torque converter transmission.
The dct on the street feels directly connected to the rear wheels.
So much so for me I would probably buy a manual over a torque converter A10 where as if a dct is made available in the c8 I'd definitely buy the dct.
To each their own of course ...and that's why the manual will be offered in the c8 as 7000 units of manual transmission corvettes each full year of c7 production...
GM is not giving up or even considering failing to attract 7000 potiential buyers of the c8 and will offer the manual transmission you desire and 7000 other auto enthusiasts prefer..
Just like the Porsche Boxster offers both a manual and a pdk and sells way many less vehicles here....and the pricing is about the same to corvette.
