Games like Dance Central will definitely drive the Kinect titles. Ellen was surprisingly good at the game and helped highlight how awesome this technology can be. I think that this is excellent marketing by MS as it shows how people who aren't gamers (and I'm willing to bet that includes Ellen) can have a blast playing a game for Kinect. Every single demo I have seen of this game shows the players completely grinning ear to ear and by-standers enjoying watching it almost as much. I am white, I do not dance. That said, this game still looks freakishly entertaining!
