I'm not sure if they are exclusive, but New Carnival Games, Raving Rabbids Travel in Time, Conduit 2, and Dance Dance Revolution will all be coming with Motion Plus support this fall.
As for Nintendo themselves, it seems they have shifted their focus onto the 3DS right now. I'm not sure we'll see much more from them, although Miyamoto did say he was personally working on something other than Zelda.
What I hope to see?
-Giant Flail-swinging in completely destructible environments
-Soccer Game (with leg straps that can hold the Wii Remote so that you can get realistic kicking control)
-Order Up 2, even though nobody played the first game. Or any cooking game that IS GOOD.
-A GOOD flying game for the Wii.
-How about Jedi Knight 3 with motionplus support for lightsaber action?
