Activision has done it again and made yet another game for us to throw our money at and it's called, DJ Hero. Besides the unvieling of the turntable style controller,  there isn't much information on DJ Hero yet but from the screen-shots it seems that you'll be able to team up with friends and use the other instruments as well. Here's a video of some of the game play.
