All but confirmed....DCT it is!

I spoke to a Tremic Rep at their Headquarters requesting additional information on the TR9007/TR7007 because I would like to perform a retrofit with it and wanted to know availability/pricing/etc and was told that this will be an OEM Trans ONLY and that one of the major US Manufacturers will be announcing shortly that their vehicle will be using this Transmission! Of course it could be any of the Big 3 but I know where I have my money lol!
When I pressed him as to would they be offering an "Aftermarket" version of this trans similar to the way they offer the T56, etc. the answer was big fat NO! When I pressed for details here's what I got...…the data bus required to operate this trans carries to much data for existing BCM's to handle so they won't be offering it. Of course this sounds as lame as someone saying that since there is no harness available for a current production engine so we can't sell one....duh....that's what the aftermarket is for. Guess we'll just have to wait and see!

.....The Mclaren 720S has 710 HP & 568 torque so does the Ferrari 488 Pista and both have DCT. Remember the new dual overhead cam high rev motors powering the faster version of the ME (Zora,Z,ZR1) could have lower torque than the C7 ZR1.
In an evenly matched race, with Racecar A touting more torque at lower RPMs and Racecar B possessing more high RPM horsepower, who would win? Racecar A will be quicker to accelerate off the line and might look as if it has the lead at the beginning. But once Racecar A shifts into second gear, it will lose its acceleratory bump. By the time Racecar A shifts into third gear, high-horsepower Racecar B will be the new leader....

Yep 99.9% it’s a DCT, packaging would not fit automatic trans in the new ME setup.

Is this supposed to make their "opinion" credible?

That C&D piece is from 2016.
More recently, in May this year they changed their opinion:

Oh, did we not mention the transaxle? (Note that we used the singular form of the word.) There will be only one gearbox, and it won’t come with a clutch pedal. Chevy has been working with Tremec on a new eight-speed dual-clutch automatic unit. The driver’s involvement in shifting gears will begin and end with the steering-wheel-adjacent shift paddles.

In looking over the specs, the TR-9007DCT is 198 lbs dry and the TR-6070 used in the current C7 is 143 lb wet - so it looks like the C8 will not be a lightweight, although it is a little lighter than the current 8 speed auto (210 lbs).

On JerriVette's other comment, the more I think about my idea of using a Ferrari type gate and sensors to shift the DCT when you want - it would appear easy to do. Flip a switch and it's "stir your own gears," whichever you want when. May not be as quick as fully auto but who cares! Quick enough. Don't need no "sticking mechanical link to the back" wires are fine!
Even could have a 3rd pedal if nothing else for take off. When I look at the computer logic algorithms used for take-off on DCTs my foot knows better. Perhaps faster movement makes the clutch engage faster etc. Whatever it does now by computer control can be simulated and controlled to some degree with your foot and hall sensor or switch.
