These grafts continue to show that WiiU's launch and continuing sales really isn't any worse (and in fact is far better) than PS3/360's.
My concern is 360/PS3 were high-tech systems that cost a lot initially (and still aren't cheap!) but because of that enjoyed the longest console life (without replacement) we've ever seen. WiiU will quickly become outdated tech-wise. Likely even by Android powered devices within the next couple years.
