New previews for Harmonix's Dance Central showed up earlier this week on the big game sites and still living up to be the killer app for the Xbox 360's Kinect. It is indeed still my only reason I would buy the thing because it looks like a blast to play with multiple people. Let's just hope I have a decent Kinect setup for a game like this with enough room for people to go crazy. New modes and new songs were announced for the game as it is expected to come out around Kinect's launch on November 4. In the meantime, there's a new trailer above and the Giant Bomb interview for more as well as other shenanigans the guys did.
