The machines are so close, it's crazy. Xbone has limited BC, PS4 has a netflix like game streaming service which actually works pretty well, but it's too expensive (Yeah, I was able to stream American games from Japan... I think they must have all versions of their PSNow store on all their servers) but if you want a variety of last gen games, it's pretty cool. Xbone has TV integration... Sony is king of the indy games right now, but MS will no doubt get a flood of phone-ish games because of integration with Windows 10 Phone. They both have super fast menus and streaming capabilities, I think sans camera, the prices is the same between Xbone and PS4 (350 dollars), but the camera is cheaper on the PS4. Of course, for camera based games, obviously Kinect is better... And, OH YEAH, there are no camera based games on PS4 yet (not until Morpheus comes out).
Speaking of Morpheus (even though VR isn't quite casual ATM), PS4 will be the cheapest serious game capable VR solution. 350 for the machine rather than 1000+ for a Consumer Version Oculus Rift which has higher minimum specs than DK2 (but, you know, not completely cheap like Google Cardboard or Samsung Gear), and probably the same price for the VR headset itself, and Resident Evil 2 Remake may becoming to Morpheus. Combined with Kinect, Hololense makes Xbone the cheapest serious game capable AR system, and they've got some good ideas for it already. I will add that VR can become AR with modifications, but it can't go the other way, because you can't block out the view on the Hololense... I don't see Morpheus being modded into an AR system, though, unlike Oculus (which has already had AR mods made for it)
Watch this movie なう。 It's legal, free... And it's more than its premise. It's not saying Fast Food is good food. Just watch it.
