Tickets for Blizzcon 2010 sold out almost immediately after they went online. The choice few (thousand) that managed to snag some tickets and make it out to Anaheim, Calif. for the convention have worn everything from clothes sporting Blizzard’s signature Murloc to some pretty impressive costumes.
Here are a few pictures from the convention in southern California — just to give you a taste, if you couldn’t make it, of what’s happening over in Anaheim.
