Major League Gaming, which is apparently the parent company of WoW Insider favorite MMO-Champion, have announced that there will be a new PC gaming circuit, featuring our favorite MMO. The circuit will have events in San Diego, from June 13th–15th; Orlando, July 11th–13th; and Dallas, October 3–5. Each event will have $22,500 in prizes -- it's no Blizzard Arena Tournament, but that's still a lot of money.
The circuit will be played on HP Blackbird 002 computers, so I guess you won't have to worry about frame rates (that thing has 1 GB of VRAM). The competition will be 3v3, just like Blizzard's tourney. Only 32 teams will be allowed to register, and you need to have an account set up on MLG's site first; registration opens May 15. They say "more details on rules and the official format will be released on May 15th" -- maybe Blizzard will let them use a special tournament server? At any rate, it looks like Blizzard may have been more successful at turning WoW into an esport than we thought.
