Because they want to sell the cars and not make a super expensive car no-one will buy. Seriously - $130k corvette?
The LS9 in the ZR1 only share a block with the normal corvette ls(3); everything else is unique: crank, rods, pistons, valves, heads, etc. This and the fact the engines are hand built, drive up the cost significantly.
Now imagine taking the same short block of the LT1, and throwing a different intake/heads/cam on it? You know, like what they did on the LS1 vs LS6?
600 HP is nothing to sneeze at . . .

Awesome, I love this stuff. As things were dying off we got a little spark. Thanks OP! Question is whether a Z06 will be on the line or not. Hoping its in excess of 600hp.

Obviously a ZR1 engine, since it's a supercharged LT1. The better question is if the Z06 is dead or not. Or at least the GS. There's no way we're going to see all 3 back. And the one that makes more sense to ax is the Z06, since a larger engine just doesn't make sense at this time. We'll find out soon enough .

I tend to agree. It is well known that the 2009 ZR1 only came to be (in addition to the then already existing Z06), because GM wasn't ready to do the C7 yet and was trying to re-energize popularity of the C6 run for a few more years. (and I am very happy they did 
)
I too believe there will only be one Z06/ZR1-level high-performance model C7 (unless of course we see a nine or ten-year run for the C7...), and I believe it will be called the Stingray L88 Code and will have this "LT4" PD SC'd motor.

IF we see 2 more models, I think this will be the Z06 model engine. I think the ZR1 will have an LT5. Same engine name as the original ZR1's of the 90's.

Back in Jan/Feb there was some info out that they planned this generation for a five year run, true or not, who knows? However, if that's the case then I would expect only one Hi Po version. Keep in mind that the ZR1 exists only because the C7 project was shelved back in '08. The ZR1 was designed and produced to keep fresh blood in the Corvette line up. This from Juechter on vid from Carlysle back in '11 or '12. It's in the vid section I think. I believe that they will not neccessarily set out to outpower the ZR1 and leave it as the classic it is. This would be good news for those current ZR1 owners down the road.
While I too have a much greater appreciation for N/A engines, Forced Induction is here to stay. It is simply the most efficient way to boost power levels and maintain acceptable fuel economy. Which is a factor like it or not. If gas jumps this coming summer like it did last summer, we will be looking at premium fuel flirting with $5/gal. If they want to keep Corvette affordable and obtainable, a huge factor in it's success, it must also be affordable to own and drive. Forced induction is how they make that happen without adding cubes and increasing fuel demands. The supercharger is the probably the most effective and reliable way to do that. I would look for this engine to produce about 100-120 more HP than the LT1.
If they can then put it into the current chassis, adding perhaps carbon ceramic brakes and fitting for a little more tire, maybe they can sell it for a base price of $75-$80K, or just a slightly more than the Z06.
This is just my opinion based on observation of the auto industry, and I do reserve my American Right to be full of Sh*t.

As for this motor... I think people are off-base trying to compare to the existing base/Z06/ZR1 structure of the C6. I think we're going to see the standard Stingray and one hi-po variant. GM would be stupid to make a $130k Corvette in this economy. Just look at how well the Vipers are selling.
