Yesterday, it was announced that Guitar Hero World Tour had secured exclusive content in regards to the equipment you can buy in-game, and locations that you can play in over time. All this is nice, but at the end of the day, it is not the equipment my people use in the game, but the music that you play that seems to matter the most in these games.
If you look at the lineups, both have a great starting set of tracks to play, and that is really cool, but beyond that what do we know? Guitar Hero has always been a mystery commodity when it comes to downloadable music for the GH games. Guitar Hero 2 had about four to five music downloads, and most of them were tracks from the first Guitar Hero. Guitar Hero III started off very slow with add-on tracks, but has picked up as of late, but it still can be a month or more between music downloads.
