This whole "in the monorail ring or not" delineator I find confusing.
When it was all Future World. The monorail ring was not a delineator of anything. Everything in the ring was Future World, and everything outside the ring was Future World.
Sure, guests tried to create neighborhoods in their own "mind canon" by lumping Land and Seas together, and having CommuniCore/Innoventions in the center as a thing. But after that, such clumpings broke down with high concept pavilions like Motion, SSE and the history of communication, and Horizons, and Imagination... all very hodgepodgey that defies making 'neighborhoods' make sense.
Well, we have official canon now for three neighborhoods that disregard the monorail ring, just like it didn't matter for Future World. <shrug>
To repeat what I've said upstream, I'd be for for all of Future World to be called World Celebration. If you're celebrating the World... everything fits. And it get's closer to the World's Fair language.
World's Fair <=> World Celebration
