Personally, I like the WiiU better than the PS4 or the Xbox One.
Not sure how it will do. Sales seem to be slow. No one ever asks for it at my store.

Nintendo is long overdue for the next NEW blockbuster title. You can't just hash the same games over and over. No matter how good the next installment of Mario Kart 32,Pokemon 54a and 54b or Super Smash Bros 27 might be it gets old.
