Any hypothetical positives which may come with Disney purchasing 21st Century Fox are grossly outweighed by the negatives. I want Disney to lose this deal.
The possibility of getting the OOT is very, very tempting though. Not to mention FF & X-Men back at Marvel. But I do see your point.
I doubt that the OOT is any more likely to come out after the Fox deal than it ever was, and FF (not even sure what that is) and X-Men is a complete nonissue that does not justify Disney monopolizing the film industry.
