EPCOT, or at least the center spine, will look very different, but I think the problem is the park will largely feel the same after this "transformation," which is to say, dated and directionless.Epcot is going to feel very different when this is done.
SSE will still be mechanically obsolete and teetering on inoperability; The Seas continues to fade into irrelevance as Nemo does the same; Imagination remains an embarrassing shell of its 80's glory; WoL is indefinitely walled off and abandoned; and the festival table thing was so poorly conceived that they canceled it and half rebuilt what they had just demolished.
And in World Showcase, Poppins was canceled, the new China film seems all but officially dead, and Harmonious was an embarrassing fiasco that only succeeded as a tax write-off. Looking ahead, multiple pavilions will remain attractionless, the promenade will continue to be a cluttered mess of food shacks, and live entertainment is no where near the level it was a decade or two ago.
New trees, paths, and LED lights are more basic maintenance than anything else, and Guardians and Moana cost too much money and further underscore how management doesn't know what to do with this park.
After so many years of walls it's all so disappointing.
