Ozzy Osbourne, the only mortal to openly challenge the Lich King's claim to the title "Prince of Darkness" and survive, will take the stage live at Anaheim Convention Center to rock the closing ceremonies of BlizzCon 2009.

Although tickets to the convention sold out in minutes, you can still join in with the BlizzCon Virtual Ticket live Internet stream or via DIRECTV Pay Per View. The Virtual Ticket will feature 18 hours of BlizzCon coverage, including Ozzy's live performance, as well as the BlizzCon 2009 exclusive in-game pet: Grunty the Murloc Marine.

Skill tree re-specialization is currently a planned feature for the Diablo II 1.13 patch, yes.

It's official. You won't be playing Starcraft II: Wings of Liberty this year, as Blizzard has moved the release date of the real-time strategy game to the "first half of 2010." No, they never dated it; but they have now.

Activision Blizzard's reason for the delay of Starcraft II is reportedly tied to the relaunch of its upgraded Battle.net service, which handles multiplayer for all things Blizzard. In a statement to the Blizzard community, the developer writes "Over the past couple of weeks, it has become clear that it will take longer than expected to prepare the new Battle.net for the launch of the game."

Blizzard calls the new Battle.net an "integral part of the Starcraft II experience and will be an essential part of all of our games moving forward." Activision CEO Bobby Kotick said during an investor call today that the new iteration of Battle.net will likely be ready "early next year."
