With all that IP? How on earth could another company possibly wade through the paperwork nightmare of literally owning Pirates of the Caribbean, Cosmic Rewind, Galaxy's Edge, and Avatar? Look at the disaster that the Marvel buyout brought with just the one Universal area.
Would it still be named Walt Disney World?
It's a hot take, for sure, with literally zero chance of that happening. With Paris still failing as Disney the majority owner, they need the Florida properties to float the entire division. A hostile government in Anaheim prevents any further, real expansion there right now.
