For me the question is, out of the retail box at the reported prices what can the Xbox do that the PS4 cannot do? From the info I have read:
-Xbox comes with kinect, ps4 does not come with the sony equivalent sony eye or whatever its called... not even sure if the eye is as functional as the kinect
-Xbox has skype exclusive and NFL exclusives, what those exclusives mean is not clear though (nfl one sounds like fantasy football integration not exclusive viewing...meh)
-Xbox has HDMI in and can function as a cable receiver
What else am I missing? DRM stuff we all know already. To be honest, Sony is sort of being coy about what they are doing--publishers will still be able to control resale of their games if they want. Don't be too quick to think Sony is going to be the free market console they are hyping to be. (This is Sony remember? They were trying to lock us in to their formats when MS was in diapers.)
-You can share your games with people on your friends list independent of physical (lending disc) restrictions.
-You can play your games on other people's consoles independent of physical (bringing discs) restrictions.
-Best-in-class controller. (Though my support of this depends on how PC compatibility plays out.)
