There have been some issues about broadcasting rights between OGN/MBC and IEG/KeSPA that delayed a few things, but now everything looks to be back on track. The season is starting on Wednesday April 4th with the first matches of the OnGameNet Dual Tournament (ODT). The other two tournaments (MBC Survivor League and the ProLeague) also kick off this month.
The Korean leagues have all been on a break after MBC HERO won the ProLeague, Savior won the OSL and Bisu took home the MSL title. We cannot forget the Masters tournament either, which NaDa won or the victorious Protoss fighters in SuperFight 5. Recently there's been little activity though, except for the MSL and OSL preliminaries which took place not long ago but now the show is preparing to get back on the road. GosuGamers gives you an overview of what's going to happen, when matches are played and how the formats have changed. The OGN and MBC leagues are pretty much set, but Proleague still remains a bit of a mystery due to the broadcasting issues. It is reported to be starting shortly though. Hopefully it will be better than ever.
