Rock Band is due out on the Wii on June 22nd, 2008 - in the US and Canada. It'll cost US$169.99 and includes drums, wireless guitar and microphone. No word on its release in other territories, and we wouldn't encourage you to hold your breath. We wouldn't be the least bit surprised if it didn't cross the pond until Christmas but fingers crossed that we won't have to wait that long.
To deflate the excitement a smidge, the Wii version won't contain any downloadable content or online play. Boo. Not entirely unexpected but still a little disappointing to actually hear it confirmed. In an effort to make up for this shortfall, the Wii version will include five extra songs. No idea what those five songs will be, but there you go.
Or to put it another way: on June 22nd, some people will be able to play a gimped version of Rock Band on the Wii. Hello Cleveland!
