Wouldn't worry about it. Things are a lot more complex than just Disney buying 20th Century. Its beginning of deals they only talked a few weeks and they haven't met recently. Talent also has a huge say in whether deals go through or not as some of the talent at 21 Century Fox television purposely was shafted by Disney and I assume would not like their ownership to go under that umbrella when reorganization is bound to happen.
I would also not worry too much about MIB.
MIB is technically Sony. As for Simpsons, I'll quote myself from the other thread:
"Very, very tentative stuff here, but this is important: "The company could not own two broadcast networks and would therefore not buy the Fox broadcast network. It would not buy Fox's sports programming assets in the belief that combining them with ESPN could be seen as anti-competitive from an antitrust standpoint and it would not buy the Fox News or Business channel. Disney would also not purchase Fox's local broadcasting affiliates, according to people familiar with the negotiations.

The only property Universal owns that's entrenched with Fox is obviously "The Simpsons", which is co-produced by 20th Century Fox Television, 20th Century Fox Animation
and Gracie Films. That last component is extremely important. Given that Disney can not own the Fox station, and "The Simpsons" is such a viable franchise it remains to be seen that Disney may absorb 20th Century Fox TV (which produces shows for other networks), 20th Century Fox the studio (good news for Avatar I guess) and parcel out 20th Century Fox Animation, because Gracie Films is
not owned by Fox. In other words, either Gracie or the remaining Fox entities will walk away with the facets that manage Simpsons production. The dicey thing for them is that distribution gets tricky as they do not own their own distribution wing anymore. This puts something like a Bob's Burgers movie (already announced) or a future Simpsons movie into a bit of a bind.
That's good news for Universal, as it keeps their Simpsons rights safe and sound. If this even happens, of course."
And of course, they're dead right now. But if they started again, Simpsons would be totally safe.
