I think anyone could take it this upcoming Gen to be honest.
Wii U lacks power but has innovation in terms of the Gamepad. Nintendo has yet to show off its potential to really change gameplay though.
PS4 has tons of power but lacks any real innovation. This could obviously change and Sony could announce something later on but as of now its a PS3 +.
Microsoft has a chance to take it in one swoop like Nintendo did with the Wii. Sony & Nintendo both left the door wide open in terms of innovation. A slightly upgraded Kinect won't be enough but if its significantly better or if they have a brand new idea, Durango could lead Next-Gen.
As of now with limited info on what's being worked on for all 3 Systems, anybody can take the win.
