Maybe for new exclusive features but you wouldn't take advantage of 4K content on a 1080p TV and correct me if I'm wrong, but could PS4 actually have native 4K developed games than upscaled?
*sigh* PS4's so lacking in the quality library of games that PS3 had. Sony's just more into making more PS4 models without thinking of exclusives which are the reason that makes it worth (otherwise multiplatforms could be played on PC and period).
We'll probably not see a MotorStorm game any time soon because the development team behind it was shutdown by Sony.
Sucky gen.
