So Zelda is potentially in USF now? Interesting. On one hand, they had almost the perfect opportunity to spread out Nintendo's biggest 3 IPs across their 3 parks: Mario in USF replacing KidZone, Zelda in IOA replacing Lost Continent, and Pokemon in Park 3.
On another hand, if Zelda is in USF and it extends around the Simpsons back toward MIB, that would do a TON of help for USF. It would greatly expand the park's footprint, help with the dead-end feeling that World Expo has, and would prevent SNW from being a dead end. And assuming that Mario Kart, Donkey Kong, and Yoshi are still on, AND that Zelda gets a ride, it would give the park at LEAST four new physical attractions at once. Heck, it would even allow Zelda to be built originally from the ground up rather than be shoehorned into Lost Continent.
Personally, I don't think this is an entirely terrible idea. If Universal wants SNW to be their "Fantasyland," than having a huge land that features both Mario AND Zelda would work so, so well.
