Have you seen all of the amazing Kinect hacks out there? MS actually came out with some really decent hardware. The move leaves a little to be desired. In terms of games, MS need to take advantage of the hardware they have put out there and get the actual gamers wanting Kinect. I feel in time, this will happen, and it won't be exclusively for social/party games.
Some of the stuff I saw on youtube is really cool. The people who create with it said that if MS didn't make it for the XBox then a piece of equipment like Kinect would perhaps cost more than $10,000.
