I just found it funny that they mentioned kinect for a pc mmorpg. Traditionally those games are designed to keep you hooked for hours at a time. I'm ready to collapse after half an hour of playing kung fu live. (Probably more a problem due to having to repeat and exaggerate all movements for the game to pick it up under less then ideal lighting conditions) I last a bit longer with gladiator duel in sports champions, but going through a 3 hour raid like that?
If they find a different way to do a mmorpg where you don't fight endless waves as fast as possible or long battles then sure it can work. Or maybe it's just meant to be an extra to dance around at the auction house? Plenty of people will love that anyway, just look for all the dance videos on you tube.
Minority report style issuing commands will get tiring fast too, considering all the repetitive inputs you need to make. But maybe it will force developers to make mmorpgs less of a grind :)
Personally it think it better to first go in the direction of heavy rain style adventures. More character interaction. Great for all sorts of (carefully directed) action sequences. Good for episodic content. You just need a nunchuck for it to work.
