Intersting one would be:
"how many people can play at the same time?" we'll see, depending on games
"how many good games will use it?" we'll see, wii seems to have a huge advance on that, and I'd go forPSmove over kinect because of the wii experience.
"can you play in your couch?" Yes for wii and PSmove, No for kinect which is a MAJOR problem to me
"is it usable in more than games?" Yes for wii and kinect, no for PSmove (unless maybe in the browser, who knows...) but yet again, the inability to use kinect from the couch pretty much ruins the point of being able to use it for menus.
