This about lines up with what I've heard.
There's no funds anywhere yet and SSE and Imagination will fight each other to see who goes first, SSE budget will be higher than Imagination's, and they're plainly indecisive what to even do outside of "figment is in the ride" because I've heard best case scenarios to the afformentioned "current ride with Dreamfinder over Channing".
The current plans on paper is that, prior to 2032, Imagination and SSE will get work and get make overs to be pretty for the 50th.
There's just been a lot of people yelling "FIRE" on social media over Inside Out 2 taking over Imagination so I had it reaffirmed Imagination is on the radar (after other stuff in other parks is done (BBTTM and DAK stuff)) and everyone's beloved little royal purple pigmented reptile is sticking around.
The rundown is: it's not happening anytime soon, I doubt EPCOT is getting much this D23 outside of Test Track, but maybe next D23 the first in line will get announced. All that's going around right now in my spheres are "figment is sticking around" "disney wants a sponsor for SSE" and "both will be redone in due time".
Just gotta sit tight for another 2-3 years. But they're chipping away at the list of stuff that needs to be done in WDW property wide before those two get their number called. But rest assured, by the end of the 2020s, our purple friend is gonna (likely) be in better shape.
That might be a disappointment to some that SSE and Imagination have to wait til MK and DAK get done before they start hammering out more concrete plans, but would you rather those two be a victim of things being stretched thin? The 17~ bil WDW is receiving is for the next decade anyway.
