Harmonix confirmed today that Rock Band will be hitting the Wii on June 22nd. It will be going for $170. The kit includes the game, guitar, drums and mic. Also standalone instruments will also be available on June 22nd also so Wii owners will have that going for them. Unfortuanatly Harmonix has said that it will be closer to a PS2 port then one of the next gen platforms. But it will not use the Wii mote at all in the instruments so thats good.

Thanks Joystiq
