It's funny how people say Xbox has cross party chat and PS doesn't. The Playstation 4 was confirmed to have cross-game chat, so that makes the claim of Xbox having a 1-UP null and void. The PS4 overall is already better than the Xbox 720 simply because Sony planned it out that way. The Xbox will still probably use it's custom architecture which will hinder it. Since the PS4 will use x86 architecture(Which for you normals means it is a console computer.) that means that developing it requires very little effort to port. TL;DR - PS4 has cross-game chat, Xbox will use custom architecture, makes PS4 considerably better. PS4 is computer in box, as already stated. Means PS4 will be superior in general.
