Careful, RedOctane, careful!! Guitar Hero II hasn’t been out for very long, and already you’re talking of Guitar Hero III? You do realize it’s going to get harder to make people buy a new copy of (essentially) the same game with every iteration, don’t you? Now that GH2 is out for the 360 featuring downloadable content lovin’, it’s hard to see why 360 owners would upgrade to a new game.

Still, this announcement is going to be very exciting for Wii owners… that’s right GH3 will be the first game in the series to be available for the Nintendo Wii, and it’ll feature online multiplayer and downloadable music (hopefully to the SD card?) to boot! Wii owners will also be getting a guitar peripheral, though it’ll be interesting to see how it incorporates the Wiimote… will the little remote be used for some sort of motion sensing? For now, your guess is as good as ours, though IGN promises to update this story later today.

Update: Looks like the interview’s already posted! Check out the link here
