I have recently seen several articles about rumored attractions coming to Epcot that include the following: Guardians of the Galaxy (replacing Universe of Energy), Tron Light Cycle Power Run (similar to the one at Shanghai Disneyland) possibly located in the old Wonders of Life pavilion, and a Ratatouille attraction (in the Paris pavilion)

Also, I have seen that Mission: Space is rumored to be getting a major rehab which will change some of the story-line.

Does anyone know if any of these are more than just a rumor at this point?
