It looks like Activision is raising the virtual rock star bar a bit by bringing in Rock Legend/Reality TV "Star" Ozzy Osbourne for Guitar Hero: World Tour. In the game you`ll be able to rock out on a virtual OZZFest stage while playing tunes from Ozzy`s tracklist like "Crazy Train". Ozzy will also join Zakk Wylde (not his birth name) from Black Label Society as playble characters in the game. No word on if a "Chasing the Dragon" mini-game will be required to unlock Ozzy or not.
