Speaking for most wanted expansion, from a business perspective, id put Valley of Peace in EU and Pokemon in USF. Pokemon would fit very well there and be a major draw besides the Wizarding World. USF needs something after Bourne desperately. I think as others have said, spreading out Nintendo means best chance to get as much $$ as possible. If you have SNW in EU, Pokemon in USF, and Zelda in IOA, you're going to get A LOT of people visiting all 3 parks. To me it just makes the most absolute sense. Plus, from what we know at least, doesn't seem like EU has many boat rides and I believe theres rumored to be on in USB, which is where the Valley of Peace will first open anyways.
