BlizzCon 2011 Girl Costume

BlizzCon 2009
On February 17, 2009, Blizzard announced their fourth BlizzCon, taking place again at the Anaheim Convention Center on August 21 and August 22, 2009.
In an attempt to reduce frustrations linked to lack of ticket availability for previous BlizzCons, there were to be four halls (increased from three) of space available.
