Speaking of Kinect, I'm really surprised they didn't show practically anything for it, especially after they touted how more advanced it was than the original during the reveal conference in May. I'm no Kinect fan, but I am one of those who are just waiting to be won over rather than actively hating on it.
I think the plan was to just announce a bit of everything to try and get everyone excited, instead of focusing on a specific portion of the market.
