From what you all might know, the current tving OSL that's airing is the last Brood War OSL ever. The OSL is moving on to SC2, along with the KeSPA teams, so here are the groups for the prelims. Only the best guy in each group qualifies. Four players have been seeded based on their GSL results, international results and current streak. Note that these prelim groups are only for GSL/SC2 players, the KeSPA players will have their own prelims.

For brackets please check Team Liquid, seems ESR has some problems formatting Korean letters. :(

Update: KeSPA preliminaries to be held on July 19th. Updated the post with qualified players as well. Check out the more detailed results on Team Liquid.
