Here's another rumor that points at just who we might be seeing on stage BlizzCon -- over on Roadrunner Records' Blabbermouth.net news website, there's a rumor going around that guitarist Gus G., who's part of a band called Firewind, will be playing with Ozzy Osbourne at this year's BlizzCon. This isn't the first time we've heard Ozzy might be there -- Zakk Wylde, who is apparently on his way out of Ozzy's band, previously mentioned that he might be playing there, but Blabbermouth says Zakk is out and Gus is in.

Now, before you go all nuts over the excitement of seeing the Prince of Darkness at BlizzCon (and we don't mean Arthas), keep in mind that this is only the second in a series of rumors, both from sources who may not exactly be familiar with BlizzCon anyway (they're only writing about this because they're interested in who's playing guitar with Ozzy, not what's going on at Blizzard's convention). So we definitely don't know for sure what's going on at BlizzCon yet -- don't pack your "Bark at the Moon" t-shirt until you've heard the official announcement from Blizzard.

Still, that would be an incredible show. I like Video Games Live and all, but they've never performed "Crazy Train" for us.

Thanks, Rob!
