At this point no attraction is immune to Disney's aggressive desire to cut operational costs or shoehorn IP wherever they can IMO.
It would not surprise me in the least if they replaced The American Adventure, mothballed Spaceship Earth or turned the Carousel of Progress into a restaurant.
It's a minor miracle that The Jungle Cruise still operates, given that it's almost as labour intensive and expensive to operate as 20,000 Leagues was.
I'm as cynical as they come, but after The Great Movie Ride, Universe of Energy and Sum of All Thrills I'm taking nothing for granted. Even having a sponsor or being around for decades doesn't cut it anymore.
