Is The Next Nissan GT-R Going To Debut In Gran Turismo?

Nissan just put together a graphic of every single one of their cars that have appeared in Gran Turismo. And at the very end sits this, their next car, under a sheet. Is it the next generation GT-R? A race car? A concept?

A quick look makes it pretty clear we're not looking at their yet-to-be-revealed Le Mans LMP1 prototype, but it does look a good bit like some kind of GT racing car.

I have a hunch that we're actually looking at a concept car, part of Gran Turismo's Vision GT program that has already given the world this Mercedes, this VW, this retro BMW, and a number of other cars.

What do you think of this Nissan, though?
