This is why I was growing concerned for the Wii in Japan, because I didn't expect Galaxy 2 to move any Wiis there, and sure enough, it didn't. The game might move consoles a bit in the West, but not in Japan, where 2D Mario vastly outpaces 3D Mario in terms of popularity.
The remedy for Wii's stagnation in Japan is Wii Party, and on a larger scale, Wii Relax. Those are the types of games that move systems there, games that try new things and draw in new crowds. Nintendo needs to keep releasing more games like Wii Fit in Japan that push the boundaries of the very definition of a game, in addition to more motion plus games that show Nintendo put some work into them.
Of course, there will be some other games, like the Dragon Quest games, Monster Hunters, and established Nintendo franchises like Pikmin, Star Fox, Kirby, etc, that may move a few units there as well. But to TRULY keep the momentum, Nintendo needs to keep creating not only new games, but entirely new GENRES, in order to maintain the Japanese crowd's interest in console games.
