I could be wrong but I am still doubtful about the level of Disney involvement in these decision. It still remains illegal for them to direct the path for Fox properties at all until a merger is signed. Which is why Feige is saying he has no plans at all (even if in his head he has). Fox could internally decide to hold off development though with the merger in mind.
This is all a big deal for comics fans but in the context of the deal worth tens of billions it’s absolutely small potatoes. If the ‘source’ is correct then Comcast could go running to the authorities with an anti-trust claim that could screw it all up.
