I honestly don't care if Nintendo uses it or not, so long as someone does. So far I have 4 games that use the Balance Board, and 2 more that I want to buy.
For WM+, I have Tiger Woods and my brother has Grand Slam Tennis. So long as someone comes out with a game, I really don't care if Nintendo does or not. Nintendo already said that Zelda will use WM+, Red Steel 2 looks interesting, and I'm sure there will be more games in the future.
