Iwata: Wii isn't in a healthy situation we need to recover momentum

[Mr Khan]

Perennials, evergreens, are the only way to recover momentum in Japan and make it stick. Everything else, all the really heavy hitters, are just flashes in the pan for console sales, as we've seen with their market reaction to all the big IP releases so far this generation. It's stuff like Wii Fit, or Monster Hunter (on PSP, at least), that has helped change the fortunes of consoles on more than a temporary basis

 

NSMBWii could be that, but not in Japan (given that little to no bump was seen for DS sales for the original)
