You have NO idea how much I’d like that. My first EPCOT experiences were in the mid '80s; the dawn of the computer age was the perfect time for exciting exhibits about how computers are going to transform the future.
The state of the Imagination pavillon is… rather sad, yes. If they were smart they’d play to nostalgia and bring much of it back; the Figment comics and anything with old Imagination stuff on it is a hot seller, so the audience is certainly there. Beyond any of these new Epcot overhauls, bringing back some gleeful childlike joy to that pavilion (including the rainbow tunnel) is by far my biggest wish.
