That's pretty "cool" looking, but I see ALOT of "movie prop" cladding on that car. I think the C7 will not differentiate from the C6 as drastically.
Look at the history of the Vette's styling. The C6 is still a relatively "new" design, hence I'm thinking the C7 will be an "extension" of that styling versus a completely new design.
(Oh, and I still prefer the new Camaro's styling.
