The latest artist announced to join Guitar Hero World Tour? Ozzy Osbourne. He and guitarist Zakk Wylde will appear in the game, due this fall, as will songs such as Crazy Train and Mr. Crowley. Those songs will be playable in a virtual Ozzfest venue. Osbourne chatted on the phone — just days before this year's Ozzfest Saturday in Dallas — with me about video games and technology.

"I had to put on this black suit with all these little ping-pong ball-like things all over me, motion capture. I had to dance around like I'm on stage when one of my songs are on. I don't really know how it works, but I have seen a run of it. It is really interesting. The image of me, I wish I had the energy it has. The graphics are really, really good. "
