The Corvette program is a complete different part of GM. This group that they are doing away with has nothing to do with the Corvette or its performance. This group takes base model cars and turns them into performance cars.
The Corvette is at this point in no danger of going anywhere, it is one of the few divisions that actually makes GM money right now. They have also did research that proved GM would loose more than just Corvette sales if they were to do away with the Corvette division. This is the reason it did not get canceled in the early 80's when it was not making money.
What will kill the top end Corvettes (ZR1 & Z06) is the fact that Dodge will no longer make the Viper. With no US competition there is no reason to make these cars with the big HP numbers anymore, the HP wars will come to a end.
