He’s been sharing info with me for about a year and it’s all come to pass.
It sounds like the May opening claim didn't end up happening at least, which was something I was given reason to suspect was incorrect especially recently (it sounds like Drew also heard something similar to contradict a May opening, and others here also suspected it was too aspirational).
I posted the tweet because I don't believe he's lying about having a source and there's always the possibility of him being correct. The renders he posted clearly seem to be real Disney creations. My issue of contention is that I strongly suspect that his renders are very old and represent a still very incomplete portrayal of the quantity of figures. And I believe his claims (or possibly whoever gave him the renders) are based specifically on the number that these renders appear to contain. He initially stated that the finale would only have 6 AA's, which is the amount shown in the renders. He later amended this number to 9 when I pointed out three other confirmed characters who weren't yet present in his renders. And as I pointed out, there is a ton of empty spaces that seem specifically designed to house a lot of other characters. Spaces that also weren't present in the movie's variant of the Tiana's Palace facade.
My own source stated confidently that claims of the AA population being low are false. I asked specifically about this and pointed out Archive's claims and renders. My concerns with the finale were again singled out and the scene was specifically described to me as having "easily as many as Splash's did". The source claims that they have personally seen final full scene mock-ups of the entire ride, not just claims that came up in conversation with imagineers. This source has also gotten a ton of other things correct about this ride and others, including some of the Epic Universe details even before Alicia Stella.
At the moment, i'm erring on Splash Archive's claims regarding the quantity being incorrect/outdated. If it turns out i'm wrong though, i'll admit that and apologize. It's going to be a massive failure if they don't properly fill out the scenes, regardless of how high quality the new figures are. I am sick to death of seeing rides gutted of their densely populated scenes and replacing them with far emptier rooms. There will be hell to pay if Disney does this with Tiana and you'll not see me defend the ride, I can assure you of that.
