In many ways, I think Comcast/Universal would much rather there be a market crash/recession NOW (people have been on edge about this happening for a few years now, anyway) than for Epic Universe to open and THEN there be a huge market and tourism crash. By 2023, we should hopefully be well past this and stabilized again, which is an ideal situation when opening a new theme park.
That's of course just looking at it from a business standpoint, obviously there are much more pressing real world things to deal with right now.
