Nothing is happening. BW has a contract with Lucas Arts, and now Disney via the buyout. There is nothing Disney can do about it unless they want to pay a hefty fine to BW for breach of contract. It also doesn't make a lot of sense, since SWTOR is licensed and that is what Disney said they wanted to do. Blah blah blah, I've said this a few times on the SWTOR forums. Nothing is getting shut down.
Peace.
