An analysis of some apparently credible leaks from Disney Central Plaza.
Big things to note: Each land looks initially to only contain a single ride with two big e-tickets (Frozen and Star Wars battle escape) alongside some flat rides and what's hopefully a better retheme than the Incredicoaster for the Rock n Rollercoaster. Looks like there's a large amount of expansion space and they've drawn up a bunch of potential plans for adding rides to the new lands or expanding them based on popularity.
It's good to know that this expansion looks to be a long term deal and not the "build and forget" approach that caused the park to get into the mess of a ~2 years ago.
