Also from reports Comcast is trying to line up investment banks to get them the money to do the deal. Its not that they have more than $60 billion in cash reserves , its just that they have to borrow to make the deal happen. Disney meanwhile seems to be setting the deal up with cash and stock , which as posted above works for Murdoch. He'll get 25% of Disney stock and that is a great prime spot.
Also without a movie studio to do films , its kinda silly to think that Fox in its next form will be able to make films and hold onto Marvel film rights. Because without a film studio how exactly do they move forward with that ? If someone says they can approach another studio to do films , well its not gonna be so easy to put a film into production.
