I have not had an opportunity to demo a Kinect yet, but I have seen stores that carry some of the release titles. I noticed a few exercise games, and a couple of dance games, and the kinectimals thing. So far, I haven't seen much to make me want to shell out the money to get one. My brother has a friend who got one in the first week they were released, and he seems happy enough with it. Aside from that, I haven't spoken with anyone else who has one.
I was disappointed to see that the bundle systems went from eight gig to the two hundred fifty gig system... and I dislike the prospect of the eight gig. After you consider how many updates, patches and whatnot you need just for the system alone without including game updates and save game files, how long is that space going to last?
More power to Microsoft for being to push over two million of them through the doors already, as the holiday shopping season has already begun I'm sure they have an ample opportunity to reach their expected sales numbers. Don't be surprised to see that they will start making reverse patches for some older games to work with Kinect in the future once they hit a wall on new Kinect-related titles to bridge the gap until developers catch up.
