That depends on the platform and on the game. A handy game car could have 50.000 faces and a PS4 car can have up to 1million in the showroom. Gameplay cars on PS4 are around 250.000 faces. Character on the PS4 are up to 80.000 and more. Lowpoly is everything viewable in realtime in a Game Engine.
I'm really really hoping this will have decent, full splitscreen on PS4. I want to play this with my girlfriend and not have to buy another PS4 and game for just that...
Woah, woah, what? I like the PS3 and think it had the best looking games of last gen but I don't think it was that powerful. There's no way PS3 is equal to PS4. The new MLB The Show for both PS3/PS4 prove that. PS4 characters have more polygons in their faces than the PS3 counterpart.
