Corvetter really don't have where to go except up. It has the power and the chassis is actually pertty good, but the balance has always been the issue along with the suspension. By moving into mid-engine, proper suspension set up, it will be true world class car. With that, the price tag will go up as well, but knowing GM, they will make it affordable as well, even if the car is over six figure.
As for the GT-R, it is really a budget issue. They didn't have to do much to the chassis since the original was already a world class chassis, by retaining a six cylinder desing (V6 over I6), it is actually a cheaper rounte. They did not have to develope a whole new V6, and the improvement of the electronics, 4wd, 4ws, only required improvment over the old system, so the developement cost of the R35 is actually not as much as let's say, a new NSX with mid-engine layout. Renault is famous for keeping the cost down, from their production car to F1 team, they are very conservative with their spending, but smart with the way they spend the money.
Other than the engine switch from I6 to V6, the car essentially just a evolution of the old, which is not a bad thing.
I just wish they can make that car a little smaller, more sleek, and with nicer interior, but my thoughts may change when I see the actual production type in person.
