It is a very ambiguous statement. Reading between the lines it seems MPNs parent company wants to stay in the business so perhaps they will just licence software OR perhaps they will run their stand alone site themselves?
32Red will join Unibet. The only network for Grosvenor to join is ipoker. However online satties for the tour has never been a big thing so maybe they just close up online. Genting are running a tour with no online side so it can be done.
Saddest for me will be MPN live tour might well stop which for me is the best live tour by far.
Unibet/GG are options.
