I'm still thinking at worst it will be something like "Disney presents Jim Henson's Muppets." I mean, Disney owns the network and the programming but they didn't caLL IT Disney's ABC.... they didn't even call it Disney Family, just ABC Family, and that's because Fox didn't own it anymore. They don't call them Disney's Power Rangers.... unless it's only cause they don't want to associate Disney with some hack kid's show like that.
As for SS changing the name, dropping "Jim Henson's Muppets" from the credits... I don't think they'd do something like that. It would be muy disrespectful, and since SS would be no where without Jim's guidence back in 1969, I don't think they'd do that... not for a while.
