We always assume / hope Disney will keep things fresh when it comes to movie based attractions.A remodel of the theaters and removal of the animatronics could possibly make this a generic space where the IP could be changed out every couple of years after the novelty wore off. WIR becomes Olaf's Alien Adventure or whatever. All one would need is to change out signage and the CGI film.
Has that ever happened before? Soarin only happened because it was in Shanghai's budget.
Even Star Tours, took more than 20 years. And it's Star Wars, something Iger cares about.
I'm still waiting for updates to Imagination theater, Muppets, all the world showcase films, Circle of life, etc etc etc
