I'll be scoring one for the wife to replace Wii+Hottest Party 3 as part of her workout routine, but as for me, I personally don't see any value in it as a "core" gamer - particularly with the absence of any real Minority Report-like UI navigation.

That said, I really want to see them go back and reexamine this tech and find ways to integrate it into past and future "core" games. I really see no reason why they can't implement some "hybrid" control schemes in conjunction with the existing controller or a separate add-on.
