Disclaimer: Sports Khan is a Korean sports/entertainment tabloid. They practice a lot of sensationalist journalism, like The Sun in the UK. This is not a direct translation, just my summing up of the story.
Mike Morhaime, president of Blizzard, visited Korea between February 24~26. Apparently it was just a routine trip to on Blizzard Korea business, with no major activities scheduled.
There was one minor event that had been planned though, a small private event at a hotel where Mr. Morhaime was to deliver the Starcraft II beta to the Korean pro-gamers and pro-game teams directly, with some time for dinner and discussion.
However, the event was cancelled, because most (the article does not say all) of the pro-game teams turned down the invitation. Why?
Blizzard Korea representatives said there were some internal scheduling misunderstandings.
The more interesting explanation though, is that it's because Blizzard did not go through KeSPA in order to arrange the event. Instead, they contacted all of the individual pro-game teams directly.
For the sake of future negotiations with Blizzard over intellectual property issues regarding Stacraft II's E-sports scene, the pro-game teams are united under KeSPA as a single party. Blizzard's treatment of the teams as individual entities could be an effort to undermine their unity on that issue.
An anonymous source from a pro-game team is quoted as saying "Blizzard Korea doesn't want to recognize KeSPA as negotiations partner regarding intellectual rights, but that's not the right way to think about it... ...KeSPA was created together by the teams, and KeSPA is essentially the teams themselves."
