Only thing I hope is that they get the sound right at some point. It's the big no-go for the game atm for me. And I don't mean specific sound for the new Premium cars, but the overall sound engine.
IMO GT6 with its 1k of cars could really use an LFS style synthesiser sound engine. Enter displacement, engine form, cylinder number and - boom - sound that's somewhat fitting. You can't expect them to record 1k cars for the game(s).
