Konami recently spoke on their upcoming music product, Rock Revolution, for all next-generation consoles.
Keith Matejka, associative producer, discussed the reasons behind focusing on the drum work, lack of vocal play etc. The game is in development for Wii, Xbox 360, PS3 and DS - with the Nintendo varieties having slightly different play to the Sony/Microsoft powerhouses.
The Wii version uses motion control for air-instrument play, whilst the DS has stylus control for some touch-screen antics.
Rock Revolution is due out in fall 2008.
