The Legend Of Zelda: The Skyward Sword.

Oh yes, this game is going to be awesome. By the way, I would be interested to know if this game has MotionPlus support. I have this hunch that it would have support for it. Also, Dazz in Link's clothing would be really awesome to see.

...lol?

The game is specifically made to utilize Motion+.
I wouldn't be surprised if the game ships with one included.
