I'm a huge Chevy fan, especially when it comes to Corvettes. This is fantastic news.
I've been on the fence for some time whether I want a Corvette or a Viper and now, I'm thinking the edge is going to the Nissan Skyline GT-R R35. I had gone to the LA Auto Show last month, had seen the new Dodge Viper ACR. Beautiful and it looks as mean as the Competition Coupe up front and with the rear wing. I couldn't help but notice that Dodge upped the ante to boost the Viper's HP up to 600+ horses. I walked across the hall to the Chevy side only to be a tad disappointed that the Z06 still had the 505 HP 427 cu in. V-8. I talked to the salesman there and said, "the boys at Dodge just increased the power on the Viper. What do you say to that?" He smugly said, "Ohhh, we have a car that'll beat the Viper and it'll come out next year...or 2009." The last part threw me off though, as we've been waiting for some time for the "Blue Devil" Corvette that promised 600 HP with a bigger block engine, but this must be it. I'm pleasantly surprised. Looks fantastic.
I'd say the C6 does resemble a Viper in some instances, but I'd say it's a Corvette that has some Viper elements mixed in with a Ferrari-esque touch.
However, my favorite Corvette of all time is the Lingenfelter 427TT C5 Corvette that had gone 0-60 in 1.9 seconds and about 8.5 sec on the quarter mile (although it was probably done on racing tires and/or racing slicks). I love it even more that it reached such unreal lines without resorting to push the engine to 1000 HP (it had roughly 866 HP) and because nothing really distinguishes it on the outside from a regular Corvette (unless you bought that lousy aerodynamic body kit).
