I expect to see something similar to what Cadillac has done, eliminate the powerful V8 replacing it with a V6 Turbo. The power is in the same league as present.
This is why I decided to buy the new 2014 now. This Golden Era of performance is at its peak. In the old days, emissions were the root cause. Today the drive to gain higher MPG's is the force at play, right or wrong.
Can't look at the Corvette too much, I think. They too seriously considered a blown V6. Yet, this is an ultra sports car in fairly low volume. GM can allow the Vette to play. I'm not nearly as sure about the Camaro. They killed it once. We cannot take for granted it will survive as is.
Understand please, I will be happiest if I am wrong about Gen 6 in this respect.
In the mean time, I'll continue to enjoy the excellence of the 5th Gen.
