[Update: We had originally reported Dance Central 2 would be launching on October 21, and while that's true for Asia and Europe, folks in North America will have to wait until October 25. Sorry for the confusion.]
The headline says it all. The news from gamescom is that you can expect to see Dance Central 2 hit on October 25. There will be 40 or so new tracks in this Kinect dancing title from Harmonix, and you'll also be able to import the tracks from the first game. Finally, there's a Dance Battle mode that supports drop-in/drop-out multiplayer.
Be sure to check out the new trailer, screenshots and character art.
