Seems like Chevrolet lets the world "catch up" to the Corvette, then surges ahead in a manner that takes almost a decade for the remainder of the pack to catch up again. Look at the past two generations, albeit the C4 was almost passed the last year, but the LT4 allowed the Vette to stay a breath ahead, then along came the C5. It leaped ahead in technology, power, and handling, now as the pack is catching up or pulled even in many cases we are about to witness another leap.
The marketing group within GM is smart, they can milk a design concept for all it's worth, then just as it's starting to get boring , they throw out another bone.
Looking around at the other major marques I suspect the Corvette group has been watching very closely to see what is going to come out the doors. While everybody is ooohing a ahhhing the new stuff, the new C6 is probably still not entirely completed, and if needed it could get tweeked so it will come out swinging [read kicking butt] the first year, and still have growth potential over the anticipated life span of the generation.
It must be getting tougher to design a lasting winner, in today's world of computer controlled engines, every manufacturer has a potential winner until sombody else raises the bar. Let's see how high the bar is raised when the C6 debutes, throughout the Corvette history, the new Vette has always brought a very big nod of approval from the media, the competition, and above all, us... the Corvette enthusiasts.
Things are just beginning to get interesting, the current HP wars could make the HP wars of the 60s look like a 1st grade scuffle by comparison.
