So it really seems a lot is being proposed for Epcot as I read around more and more. To simplify things, here's a list from Martin compiled over on magic recently (he was commenting on someone else's post... the bold is his text):
- Energy is getting a GotG overhaul, green lit.
- Wonders might get a GotG phase 2, or something else. Or be demolished.
- Communicore (outside of mouse gear) will be updated/overhauled, green lit. Including Mousegear
- Mission Space will get a refurb/update, green lit.
- There are plans for Imagination, but not green lit.
- Land might get a update, but not green lit. will get an update
- Seas will remain as is wrong
- Test Track will remain as is
- Space Ship Earth will remain as is wrong
- Disney Pixar Short Film Festival to get replaced with Inside Out (Part of imagination plans), but not green lit. Wrong
- Brazil Pavillon, but not green lit.
- Ratatouille Ride in France, green lit. Not green lit.
- Coco For Mexico, Not green lit
- Ride for UK, Not green lit
- Replacement for Illuminations. 2017-2019, Green Lit. Didn't I post those dates like 3 hours ago?
As far as World Showcase goes, the most likely things are Illuminations update, Coco overlay in Mexico and Rat ride. New Country (Brazil or ?) and UK attraction (Anywhere from B-D ticket) are also looking likely.
As for Future World, there's a lot there as seen above, but attraction wise, Mission: Space may see an update as early as this year.
