EPCOT has become a headache for Disney.
https://insidethemagic.net/2020/05/epcot-disneys-biggest-problem-during-closure-rwb1/
Main speculation and thoughts to point out in this writing...
-Future world is torn up. Construction will certainly be delayed. The Mary Poppins and Moana attractions as well as the rumored Brazilian pavilion may all get scrapped completely.
-The Ratatouille and Guardians attractions are likely to open eventually as those projects are already beyond the half-way marks.
-The face mask requirement is going to be detrimental. Not just because their use and enforcement is highly controversial, but EPCOT is a park where eating and drinking is part of the fun. Every country pavilion has restaurants, quick service, food stalls, places to buy food and drinks. The masks would be coming off constantly.
I also think it may be difficult to reopen as World Showcase relies heavily on foreign workers, internships, and the college program. It could be sometime to get those workers back. Disney has also ended many contracts for EPCOT entertainers. They can be resigned or new people can be found, but that doesn't happen overnight.
It will be very hard for this park to be profitable anytime soon. The company as a whole is projected to lose a total of $13 billion dollars if the closures extend to July 1. And attendance will be impacted for months or even years to come. Many Disney fans have already started to avoid EPCOT even before the pandemic due to the heavy construction around Spaceship Earth. Now add in various restrictions and limitations and reduced experiences and many more will decide the value just isn't there. EPCOT may have a bright future, but it will be rough for quite awhile.
