Yeah... If DisCo has learned that "edutainment" gets old... DisCo dun lernt rong.
What doesn't work is pavilions reliant on sponsorship (Hornizons, World of Motion), and films/shows (Magic Journeys/EO/HISTA, CoP/America Sings, CircleVision, etc).
Three variations on my dream would be to a) clear out some backstage area, create a small Edison Square area off Main St. which serves as queue for a new Carousel of Progress, which exits into Tomorrowland, where Horizons takes over in the Carousel theater and possibly some adjacent space, b) similarly, since these two attractions are so closely related, it would be great to see them as centerpieces of a third gate I've long refered to as ImagiNations, a revamped vision of Epcot, or c) when the Chevron obligation is up, turn the whole Subs/Autopia/MBC land into SeaCastle, a giant outdoor model city, at the center of which could be a revamped Horizons (revamped because issues like AgriFuture, undersea living, land transportation, etc., will already be addressed in new Hunny Hunt-based Autopias, Aquatopias, a reworked Sub ride, and of course the PeopleMovers/Monorails).
In any case... yes, I wholeheartedly welcome bringing real rides back into Tomorrowland, as well as rides that celebrate... Tomorrow. And, since Horizons no longer exists at Epcot, it would be the first attraction in a long time that is not a clone. Nor is it tied in to anything but another Disney original, CoP. Makes it an A+ candidate in my book.
