If I remember correctly from a recent-ish Cedar Point thread, they're replacing their staff dormitories and upgrading some electrical infrastructure. That park appears not to have any coaster in the pipeline for the immediate future.
I think we can also rule out Six Flags in general for this one, with even Gerstlauers being out of their budget. I don't see it going anywhere in Orlando either. Busch Gardens might have the budget, but we know BGW has other plans in the pipeline and BGT still has Iron Gwazi to milk for another few years. King's Dominion might have shot for that record a couple of decades ago, but now they're toying with that S&S Free Spin. Kings Island might not be likely to add a new ride so soon after Orion. Likewise, Hersheypark still has Candymonium being too fresh to start thinking of another coaster already. Any lesser Cedar Fair park is too neglected to be considered a likely candidate here. Canada's Wonderland could have been a candidate, but it's not in the US. Knott's Berry Farm has no space. (no kidding)
Maybe Holiday World? Their latest big investment was Thunderbird back in 2015. The park is obviously capable of building such big coasters, but haven't done so in a while. They've never had a Gerstlauer coaster either. Silver Dollar City is another candidate fitting the same criteria, although with a more recent investment in the form of 2018's Time Traveller, and that huge Rapids ride it built last year which means 2022 might be too early for another huge coaster.
