Nidzumi Writes : Today Activision have announced how Guitar Hero On Tour will work. In case you haven't heard, On Tour is a spin off for the regular Guitar Hero game as it will be on the DS. Well the games main obstacle is and always has been how the game actually works. Personally I was thinking an Elite Beat Agents clone but we've seen enough of them done wrong recently. What we will get is a grip controller that plugs into the GBA slot.
