Nintendo managed to mimic 360 pretty well,if we go by the public data.
They have one big problem though--expensive touch screen controller.It may turn out to be something totally pointless(like 3D in 3DS--not system seller) or hot new must have thing--time will tell.
One thing is for sure,it will forever balloon WiiU price.
Cheap,reliable,profitable might be a problem if the market says meh...
