If you've already finished Guitar Hero III: Legends of Rock (Xbox 360, PS3, Wii, PC) and are now looking for your next conquest, this rumor might interest you.

On G4's TheFeed, it was mentioned that one of their sources has given word that Activision is conducting testing for Guitar Hero IV already. Allegedly, the first round of testing is a small-scale test which involves about four to six people.

If this proves to be true, then we might be seeing a sequel to the popular music game sooner than most players would have expected.

Activision has not yet commented on this and for all we know, it could be nothing more than testing certain downloadable content for the game. Rest assured, we'll be keeping our eyes peeled for any developments regarding this rumor.
