Joystiq writes: "Activision and Nintendo briefly demonstrated Guitar Hero: On Tour at last week's Nintendo Media Summit. As previously announced, the portable rhythm game includes a four-fret controller that slips into the DS GBA slot. A stylus shaped like a guitar pick can be stored inside and pulled out for portable rocking.
Guitar Hero: On Tour includes the same kind of career mode and single-song play as Guitar Hero III; many of the portable songs also overlap with other versions of the game. But 20 new tracks, a few control twists, and a new versus mode should make it more than Guitar Hero Lite."
