I may get some flak for this but I dont think Pokémon at USF is a winning combination. Pokémon is just about one of the largest franchises left that has been untapped in the world of theme parks, that there's so much money to be made if you do it right and they should put their A-game into this.
I agree USF needs a big ticket draw because it will look a bit lacking compared to EU and IOA. But the layout of that park is just too weird to fit another large cohesive land for an IP as massive as Pokémon and do it justice. Pokémon going into the narrow strip of land that is currently Springfield has always felt too small time when it should get a highly themed area as immersive and mindblowing to see in person as Super Nintendo World and the Wizarding World.
I do think they could've done this right had Pokémon taken over Kidzone and been an enclosed land, but that ship has sailed with it becoming DreamWorks.
