I believe that one of Chevy's biggest issues with the Camaro, beginning way back in '67, was how to keep the performance up so as to compete with the rest of the muscle car market and at the same time, not dig too deeply into Corvette sales - an issue that Ford, for example, with the Mustang doesn't have to worry about.
Case in point, when I bought my '95 Z28 (still my daily driver) new in January 1995, I paid $18,022 total to the dealer. For that very reasonable price, I got 90+% of the performance of the '95 Corvette. Same engine (LT1) and same 6 spd manual gearbox with 3.73 posi rear end. Chevy purposely restricted the intake somewhat and unlike the Corvette, the Z28 did not have a true dual exhaust from the engine back. So net engine HP was a little de-reated from the Corvette, but not seriously - and all for less than 1/2 the cost of the 'Vette.
Chevy will be struggling with the same issues here. If they do indeed make the car, and put the LS2 in it, you will have a vehicle that will be about the same size as a 'Vette, with basically the same drivetrain. If the Camaro is to go back into production aimed at the same market as before, Chevy will have to price the Camaro appropriately. The same old issue will be there: striking the balance between pricing the Camaro "with almost Corvette performance" appropriately in order to compete with the Mustang, but not priced so low as to create Camaro buyers at the expense of Corvette sales.
