Blizzard has canceled BlizzCon 2012 due to what they say is a "jam-packed" schedule. The normally yearly convention dedicated to all things Blizzard will continue in 2013.
Blizzard informed fans today on the official blog. "We're also heavily focused on getting Diablo III, Mists of Pandaria, and Heart of the Swarm into players’ hands as soon as possible. In light of our jam-packed schedule, we’ve decided to hold the next BlizzCon in 2013."
It is highly likely that Diablo III and Heart of the Swarm will be released before the convention continues in 2013, so it's possible that a release date for the highly anticipated titles could be announced at E3 2012.
Blizzard isn't leaving fans totally in the dark, however. Asia will play host to the 2012 Battle.net World Championship, featuring this year's StarCraft II and World of Warcraft Arena World Championship tournaments.
More details about the 2012 Battle.net World Championship and BlizzCon 2013, including specific dates and locations, should be coming soon.
