In a press release just sent out, Blizzard has announced that there will be no Blizzcon in 2012. Rather, there will be a different event for them to focus on, the 2012 Battle.net World Championship. This event is set to take place on around the end of this year in Asia (aww, boo!) with StarCraft II and World of Warcraft Arena World Championship tournaments.

Check out the official Blizzard page for the event!
