I wonder if Cirque will be around in 10 years. Stage shows are vulnerable to cost-cutting around stage talent. And as much as many people love stage shows, I also think a lot of guests don't even count them when they list "the rides" in a park (say, compared to if there was a Fantasyland/Mystic Manor style dark ride there). It takes an "attraction mindset" to value them.
Plus, ten years form now, will Fantastic Beasts have any resonance? Will they perhaps "pull a (Disneyland) SWGE" and revert the land entirely to the O.G. franchise (of course, the new attraction will influence that possibility one way or the other).
