"World Tour" works with older "Guitar Hero" guitar controllers. Activision stated during their E3 2008 press conference that Xbox 360 users would be able to use the existing "Rock Band" instrument controllers as well as other third party controllers in "Guitar Hero World Tour"; "Rock Band" instruments for the PlayStation 3 are not guaranteed to work in "World Tour", though Sony is attempting to help make these units compatible. All "Rock Band" original Harmonix instruments for PlayStation 2 work with "World Tour". According to issue 027 of the UK's "Official PlayStation Magazine", all "Guitar Hero" and "Rock Band" PS3 controllers are cross-compatible with all games (except for "Guitar Hero: World Tour" drums on "Rock Band", however some require patching, which is done automatically when connected to the internet). PlayStation 3 instruments also work on the PlayStation 2 versions of "World Tour", as well as later "Guitar Hero" games.
