I assume that you only putting things on the first page that have been officially announced?
Because you know how much you and I peruse the wdwmagic forums. If you take into account the list you have so excellently produced on the first page of this thread, and combine it with the other things being "discussed", WDW potentially has a TON of things going on:
1) Ellen's Energy Adventure gutted and turned into a large E-Ticket Guardians of the Galaxy attraction with possible walk through area.
2) Major upgrades/improvements to the Mission:Space E-Ticket.
3) Total overhaul of the Epcot entrance and Communicore area - both East and West Innoventions including new experiences and restaurants, as well as removal of the tombstones out front and the addition of trees, plants, more organic spaces all the way through to the front of World Showcase.
4) Removal of Stitch's Great Escape and replaced with an all new Wreck It Ralph attraction in Tomorrowland.
5) Gutting of The Great Movie Ride to be replaced with a true E-Ticket trackless ride based off of Mickey Mouse's greatest moments in cinema.
6) Possible addition of rides in World Showcase.
I believe that in each case, this info has been provided by user marni1971 on the wdwmagic boards. Everyone that visits those boards knows that he has the best connections of almost anyone other than the famed spirit himself (user WDW1974). In fact, if you look at a lot of what he has said lately - and he has been posting a ton recently - there is potentially something big happening with Epcot that could stretch over the next 4 to 8 years, that even has things like Imagination being redone, multiple rides being placed in World Showcase, removal of the Lion King movie in The Land, etc. It was also stated by him (rather emphatically) that somethings may be announced rather soon, and that some of the changes might be occurring simultaneously to when the new Star Wars Land is being constructed.
Typically, I reserve judgement when certain forum members on the wdwmagic boards throw rumors out there. However, with marni1971, he has such a proven track record, that with him I put more stock into what he says. I am excited for what he is hinting at with Epcot, as I expect many of the above things to happen.
