Epcot just got Guardians, Rat, Moana walk through, a face redo of former Future World, and a significant redo of Test Track. That's some fairly major stuff in the last few years. Heck, if Universal did that much to the USF park during that time frame, I'd be jumping through hoops. So I'd think
the most we can hope for Epcot would be partial redo's of Spaceship Earth or Imagination, probably not both.
