I think it will be more dependent on the economy than the virus. There will either be herd immunity or a vaccine at some point, things will get back to "normal", but if the economy is really bad and they push EU back more than 5 years I could see them following the original plan and just adding Nintendo to replace KZ. They'll want something new that will draw people, and if it's not a billion dollar park, it's a more modest new addition.
