Early 2012
From MMO Champion (from interview with Ilja Rotelli, Blizzard's Global Director of Community & eSports, by Team Liquid):
 * The prize pool will be comparable to the Battle.net continental invitationals in 2011.
 * Qualifications will begin in Q2 this year.
 * The entire 2012 season is going to be played with Wings of Liberty.
 * There will be five regional championships, with the final being held in Asia.
 * There will also be national championships before the regionals.
 * Blizzard won't be running all of the matches, instead they will be working with existing eSports organizations.
 * There will be more matches and ways to see them than there were for BlizzCon 2011.

The World of Warcraft Arena World Championship tournament was also to be hosted, but at the end of the year in Shanghai, China. It took place on November 17-18, 2012.
