A new Guardians of the Galaxy themed roller coaster will be coming soon to Epcot's Future world area of the park within the following years. It will somewhat replace Universe of Energy, meaning that while the original attraction may be gone forever, this new attraction will feature an EPCOT-centric story. Additionally, the solar panel-lined building will still be intact but will now be used as a queue area, with the ride itself to be housed in a newly-constructed building connected to the original building by a passageway.
This attraction will be open in 2021, around the time Walt Disney World celebrates it's 50th anniversary 
As shown in the concept rendering of the attraction's exterior, Rocket and Groot are seen talking with Guests.
