Blizzard have announced that their massive annual convention won’t be happening this year. Instead, they’ll be devoting more time to finishing their many projects. “In light of our jam-packed schedule, we’ve decided to hold the next BlizzCon in 2013,” Blizzard say in a statement on Battle.net, mentioning that they’re currently “heavily focused on getting Diablo III, Mists of Pandaria, and Heart of the Swarm into players’ hands as soon as possible.”
