Since Disneyland has recently launched a newly enhanced version of Fantasmic! (which I did see recently, and it was a great enhancement although I miss the original 1992 version), I do got a feeling that Disney World's version at Hollywood Studios will also get its own enhancement too. They haven't thought of it yet, but I bet they will by the next decade.
I'm already imagining the similar enhance changes to the familiar sequences, as well as new sequences in place of some older ones. Like the songs Be Our Guest, Part of Your World, and Under the Sea playing huge parts in place of the bubble montage.
I haven't thought of a new sequence that would be in place of Pocahontas, but maybe one where Mickey would enter into the world of Frozen with the song Let It Go. But you guys may not like that idea since most Disney fans are getting tired of Frozen being frequently used in the parks and merchandising today, but feel free to reply on a better idea of either adding a new scene for Pocahontas' replacement, or just enhance the sequence instead.
And they might do some changes to the villains, like I was mostly thinking of both Captain Hook and Dr. Facilier, in place of Claude Frollo and Hades.
That's all I can imagine for now, and I'm expecting this to happen if they think about it.
