I don't know, but they had better be making one. It's been one of the biggest hopes for the system, and even the lightsaber games with the regular motion control have been hits.
My brother prefers the HD sytems, but even he says that would make him a Wii convert. About the only people who don't like the thought of this are the most blind Wii bashers*.
So basically, I really hope Lucasarts is working on one. I don't even care if it's the prequels, it would be a hit.
Now The Force Unleashed 2 could be that, but has it been announced to have Motion+ support?
*I mean the level I haven't even run across online outside of trolls. I met some really blind Sony fanboys at a store who, before the Wii launch, actually said "Who would want to play with a lightsaber game?".
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
