Blizzard finally confirmed what most of us already knew, Ozzy is going to play at BlizzCon. The first hint something was up when Ozzy showed up in the commercial for World of Warfcraft earlier this year. If you haven’t seen it, we found one through Youtube.

Ozzy Osbourne, will headline the closing concert at this year’s BlizzCon®, which will take place August 21-22 at the Anaheim Convention Center. While tickets to the convention sold out in minutes, a live Pay Per View event will be available via Internet stream and in HD on DIRECTV.

The largest event of its kind, BlizzCon is a celebration of Blizzard Entertainment’s Warcraft, Diablo®, and StarCraft® game universes and the global player communities surrounding them.  At the closing ceremony on August 22, Ozzy will unleash a thunderous spectacle of rock to put the Lich King in his place and cement his own title as the one true Prince of Darkness.

One of the most influential rock musicians of all time, Ozzy Osbourne rose to prominence as the lead vocalist for Black Sabbath before embarking on a multi-platinum solo career. He is also known for putting on the Ozzfest music festival and for starring in his own reality TV show. Ozzy Osbourne’s career has spanned four decades and his music is as relevant today as ever. The Grammy Award-winning Rock and Roll Hall of Famer has sold over 100 million albums worldwide--50 with Black Sabbath and as many as a solo artist--and in 2003 was honored with a star on Hollywood Boulevard’s “Walk of Fame.”
