Given the circumstances, none of these delays surprise me.
Construction is indefinitely stopped so obviously 2021 projects like Tron, GotG and Play would fall to 2022.
I don’t see this as a sign of Epcot not reopening this year necessarily though. MMRR already opened this year, so they already have a new attraction to promote that was open for all of 11 days before the parks closed. I see moving Remy as giving them a 2021 attraction since they were losing GotG and Tron to 2022.
As far as the hub goes, I wouldn’t be surprised if they’re trying to figure out a way to keep the still standing side of InnoWest and move Moana to the demolished section.
