The Fox board is set to meet in July to discuss the potential sale options and the fact that the Justice Department has already given approval to a purchase by Disney will likely go a long way in helping make a decision.
Fox would have the choice between the guaranteed money from Disney or the potential of more money from Comcast, with the possibility that deal could be killed by the Justice Department.
If the government had waited to give its approval then the Fox board would have to pick one of two options that were both only potentials.
Even if Comcast makes the decision to up its bid for Fox and Comcast offer more than Disney once again, that deal would require its own government approval.
