I read somebody thinks Wii Fit U and Just Dance U could "save" Wii U, but I have a doubt: while I can see some uses of the tablet with Wii Fit, I really can't see how it could offer any major advantage to dance games, it could be instead a hindrance to them, as the position you keep holding it is never assumed in partner dances and almost never in solo ones, and even in this case, only for short times.
