Throwing my hat into the Fantastic Worlds prediction pile...
- Entry area is World Crossroads. A small plaza beside the park's mountain-themed park icon, that cleverly acts as both a picturesque focal point for the park and as a divider between the worlds.
- A huge draw of the park is Super Nintendo World; a packed 20-acre world featuring Nintendo Plaza in the center, which leads into the lands Mushroom Kingdom, the Kingdom of Zelda, or Pokemon City.
- The most family-friendly area is the World of Dreamworks; featuring the quaint worlds of Shrek, Kung Fu Panda, and How to Train Your Dragon, tied together by the DreamWorks Center.
- The thrill center of the park is Sci-Fi World, a wondrous city of tomorrow that contains districts based off Star Trek, Godzilla, and Doctor Who; the centerpiece of course being Sci-Fi City.
- Of course, Wizarding World of Fantastic Beasts, featuring three separate areas based off iconic locales from the franchise, tied together by a unique indoor plaza themed to Newt's briefcase menagerie.
So basically, each of the main four worlds includes three mini-lands and a plaza in the center to tie them all together. I'll possibly go more in-depth with attraction ideas later.
