The Ps4 will have better frame rate, better graphics, and be faster than the xbox one games wise. The XB1 will be faster with other, none gaming stuff, like their t.v. integration, multitasking, and internet. So basically, the Ps4 plays games better and faster than the XB1, while the XB1 does everything that involves multitasking and t.v. integration better and faster than the Ps4. This is what the Devs mean by saying all the stuff they have been. Example: Skyrim works horrid on the Ps3, great on the 360. If you put a game on the next gens that is like skyrim, it will probably have better frame rate and graphics,(Maybe, if the devs want to with the graphics), than the XB1, pretty much any game will work better on the Ps4. When you would search for something on the internet or channel surf,multitask, or just on live shopping for games, it will run smoother and faster on the XB1. Thats it, that's how you pretty much sum it up. To be honest though, you probably won't even be able to tell a difference between the two, of course if the devs are just over reacting, if not, then these will be noticeable.
