Assuming I'm able to get a 360 I will be getting either this or Rock Band for that, depending on the final track list, because downloadable extra songs are definitely coming to those, as opposed to only being a chance on the Wii, and space isn't as much of an issue with a hard drive than the current setup on the Wii. Actually, if Nintendo confirms a hard drive is coming and Activision confirms the Wii will get downloadable content I'll get GH3 for the Wii, because I don't care about the drums or vocals aspects of Rock Band.
