It looks like Sony getting on the innovative game controller bandwagon with their hand movement controller, which looks like it's another attempt at creating gestural interfaces. I think that with the popularity of the Wii, a gestural language will develop for controller usage (check out the names for ways to hold your Wiimote in Warioware:Smooth Moves [thanks Mike and Erika!]) and that new controllers will flow out of that, rather than out of core technologies. Still, all-body gestural commands are becoming more popular. Software invocation through movements is coming.
