This is kinda what I was getting at when I said I think there's a possibility they come to a deal to extend the Simpsons rights.
Disney is pretty tied up for at least the next 5 years, and I don't think they'd fast track anything for The Simpsons in front of what has already been announced.
Anything is possible, so I could totally see them extending the rights to 2030/2031 to buy a bit more time. (Hopefully that would at least come with some kind of refresh/refurb for the ride)
