Not entirely true. The mandatory state shutdown wasn't until March and while they didn't get a timeline on reopening there was a spool up of readying rides and staffing in anticipation of a potential August opening opportunity. Ultimately that didn't happen beyond the campground operation, but it's not like they've been sitting idle the past year until the State guidance came out.
Predator needing track repair I wouldn't call an indicator that it doesn't open; it usually has about a hundred feet that gets extensive rebuilding every year or so. Definitely a fantasy to think they'd do track conversion when the ride that's bought and was ready for assembly was deferred, though. (Batman was an entirely different circumstance before folks get started on that again)
