The Overwatch League was first announced during Blizzcon 2016. The announcement came as a big boost to Overwatch as an esport. But with several months already having passed, there has not been any more information regarding the same.
Organisations and sponsors were being increasingly frustrated with the lack of communication from Blizzard’s end, there has been some information leaked by Blizzard.
The SBJ is reporting Blizzard is seeking $2-5 Million from team owners to buy into OWL, upto $10-15M for 'LA' spot.https://t.co/iRwzIrOUae

In a report on SportsBusinessDaily, the RoadShow for the Overwatch League is already underway. The launch for the league is already on schedule for a September launch.
You probably understand the amount of legal work that goes into doing this, and that time between BlizzCon and today has been spent finalizing legal documents.
