The Reunited organisation was closed on January 9th as they felt the need to focus on more established sports. At the time of the announcement there were speculations this might be due to pressure from Blizzard owing to the upcoming Overwatch League. This also points to a very unknown approach from most of the esports organisations who are invested into Overwatch right now. There has been little to no communication from Blizzard regarding the details of the Overwatch league.
Organisations do not want to invest money into an esport that will not give them value for their money in the years to come. As such any big move into Overwatch competitive scene will be preceded by a significant announcement by Blizzard.
