They have not acquired it. They want to, but it will have regulatory hurdles to get past before the merger goes through. I don't think they should allow it. Disney is already huge and giving them Fox will mean far less content is made and far too much legacy content is concentrated in the house of mouse....and that's just on the movie side, but they'll also get all of Fox' cable assets.
Sell it to someone else.
Don't fool yourself, it will get approved. We're talking about the company that bought extensions to the copyright system and a current government that is pro big business and pro merger. The FTC and DOJ might impose some llimits and rules on Disney to make it look like they're being fair, but it will go through. I'm just glad it wasn't Comcast or Verizon, as they were the other two looking to pick up Fox assets.
