I'm a little late the to game here. But, I originally thought the Z06 would be a dead issue as well as any updated version of the LS7. But, it seems that I'm wrong. I found a thread that said the newly updated LS7 will be 600 bhp and the ZR-1 will be 700 for the C7, if all goes well. Here's the thread:

It seems they will be using direct injection. But, I don't know if they'll be using cylinder deactivation. Even though, I believe, it's already been designed into the LS3.
But, I'm betting it'll take at least 2 to 3 model years before these specific variations are offered.

I'm gonna go out on a limb and say that yes a Z06 is a certainty, and it will be powered by a 550-575HP Supercharged LT1 aka LT4. That seems like the most likely route. Now what I really want to see it a halo, ZR-1 level Vette that uses that same LT4 with some forged internals to cope with a higher redline and pushes 600HP mated to a system like Ferrari's HY-KERS setup with a 200HP electric motor. For those not familiar with HY-KERS check this out:
It's a pretty basic video but the principle is based on the KERS (Kinetic Energy Recovery System) but the way Ferrari is doing it, nets a total of 950HP, using a 750HP V12.
On top of this GM can tout the fact that it's top of the line highest performance car has better emissions than the Z06 variant and make the tree huggers happy!

One of the biggest issues, I think, with the high performance European cars is their gas mileage is pretty poor. Except for Porsche, a lot of the engines from there making 450 bhp plus only seem to get a average of about 13 mpg or so. I have a friend with a 2003 Maserati GT with 4.2L Ferrari V8 engine (390 bhp) that only gets 12 mpg or so, even with it's 6 speed transmission. When I told him my Z06 is averaging well above 20 mpg in combined real world driving, his jaw hit the floor.

The 4" stroke 427 LS7 used in the COPO Camaros has a 7500 RPM(suggested) redline......just begging to be shifted! The same redline as the shorter stroke 327 supercharged versions used in the COPO Camaros.

I don't think that the intake valve needs to be smaller. I think the designers move the sparkplug off to one side and put the DInjector besides the SP. You still end up with a combustion chamber whose valve sizes are limited by bore just like w/o DI.

I believe there are displacement taxes in Europe, which is why they tend to make the power from tiny displacement. I could be wrong, though. What just makes me irrate is that they try to bill that as somehow superior to the American way of making power when all it is is different.

Remember that the GM performance division was disbanded during the bailout - so there very well may be no super-variants in the pipeline (either Corvette Z's or Cadillac V's).
However, CAFE standards are a numbers game: if they can sell enough fuel efficient models overall, there's very little penalty to producing a few (high priced), inefficient monster Corvettes.
There's nothing keeping them from reusing the LS9, LSA, LS7, or other variants for high HP applications - outside of the standard R&D costs (which are huge). However, given the volume numbers of the Z06/Zr1's since the Recession started... I would not be surprised if they scraped it altogether. Nonetheless, I hope they make at least one Z variant...

For clarification's sake: the Hi-Po Corvettes haven't ever come from HPVO, or any of GM's previous "high performance" internal shops. You're right re: the CTS-V, but not the ZR1. That was done entirely by team Corvette.

I know there are many who disagree with me BUT...the sales of the new Stingray will be so strong that adding a HP model will make total sense. It is like taking the initial investment turning a good profit then building an even more profitable car.. Not to mention the star power for the bow tie brand...

Hopefully, now that GM has paid off it's legacy union expenses as a lump sum using the TARP funds, they can start making the specialty vehicles that will really wow the market. It was very difficult when they were a health care supplier that just happened to make cars and trucks on the side.

A ZR1 will also likely be built, but turbos are not gonna happen. The supercharged Corvette is the image people have of high hp Corvettes so Chevy will play it safe and stick with SC options. I still think that a hybrid system will be the way Chevy goes its a very potent combination, and the PR machine will love the ability to say that the top of the line performance Corvette is "eco friendly".
Purists will likely lose their minds, but if McLaren, Porsche, and Ferrari all think the hybrid model for their ultra performance models is good, you can bet Chevy has taken notice.
