Facts??? I guess. Invented applicability.
This is not an active project in development. Armchair imagineering, maybe? Reaching, definitely.
Well, my point is we don't know. That's why it's labeled as a rumor. We'll find out when or if it's ever announced, but I think I provided enough circumstantial evidence for why it shouldn't be ruled out. The trick in guessing is to try to think like an Imagineer and like a Disney executive.
I guessed at an Avatarland way before the announcement, but I shrugged it off as a possible WDI project because it was a Fox movie, not a Disney film.
