Best case scenario:
GMR stays where it is and gets plussed. True trailers are restored to the preshow (and not the talky things that mimic the stuff that comes before the listed start time that are so annoying that you strive to get at the listed start time on the button even if it means sitting in the very front row). Tarzan scene is replaced with a James Bond/You Only Live Twice volcano/ninja invasion scene.
TOT stays where it is. In both coasts.
GOTG goes where it belongs. Left coast, into a 3rd gate that also has the Star Wars Experience (where that belongs). Swamps, into Islands of Adventure.
Energy is updated to something that maintains the theme of Future World at Epcot - if IP is used it's done tastefully and in service to the theme of the pavillion.
