the wii u is a next-gen system, because it does indeed do things that the other 2 current systems cant do. can either the xbox 360 or ps3 do co-op with each player having there own screen while playing black ops2 on the same console, besides the wii u. the answer is no... the wii u as well, has a controller that is truly a next-gen experience and only ppl who really put time into the system, can actually understand what i mean by that.
i am sure the next xbox and ps4, will have graphics that are truly impressive and other cool ideas, but they also need more than a in your face showcase of power in graphics, for me to be impressed or call them anything but a graphically upgrade and not a true catch your eye experience. i also dont want the ps4 or next xbox controller's to have a screen on them, because it wont feel fresh at all, but a copied idea.
i want cool new ideas on a console, i think all 3 can and will bring those to the plate. if all 3 dont do that, then i wont buy all 3 systems with my money. or will i develop for them either down the road.
