Pretty sure it would be similiar to Marvel Super Hero Island at Islands of Adventure where they have attractions based on specific characters with their own universes like Spider-Man, Storm, Hulk, and Dr. Doom. Trust me, it's called Super Nintendo World, not Super Mario World. They would not live out other Nintendo fans who are not big on Mario and his pals. The Zelda phase would have likely to come sooner or later, possibly as a replacement for the staggering and outdated Lost Continent.
