From Blizzard Entertainment:
BlizzCon is a celebration of epic games, a gathering place for our community from across the globe, and also the definitive place to see the greatest competitive matches in the world as the top pro players go head to head both in the World of Warcraft Arena and in Warcraft III. With the launch of StarCraft II: Wings of Liberty, we feel it’s high time to expand that set list -- BlizzCon 2010 will play home to a 16-player StarCraft II invitational tournament!
Top players from each region's ladder will be invited to compete against each other to prove who truly rules the Koprulu Sector and to see who will take home part of a prize pool worth over $40,000.
Check back soon for more details and official tournament rules.
