Hmm- if I had to guess, I would say...Cedar Point. They were rumored to get a new coaster in 2021, but it was supposedly delayed due to COVID, and this thing is supposed to be big and break records- Cedar Point loves that stuff. HangTime at Knott's Berry Farm was apparently very well received in 2018, so it is possible that Cedar Fair now wants a even bigger and badder version for their flagship park. Sorta repeating what happened with Xcelerator and Top Thrill Dragster, in a way. As for what record I expect to be broken: # of inversions, most likely. We are probably looking at a ride with 14+.
As for where in the park I'd see this, survey markers were seen around the Antique Cars in Frontier Town in 2020. Hence the "space" challenge that was mentioned by Gerstlauer. Though if this new ride is in Frontier Town, that really isn't gonna help draw the crowds away from Maverick and Steel Vengeance since the new ride will be in the same section as them, so now there will be 3 rides with crazy long lines (unless the Gerstlauer ends up having great capacity but even then it probably will have long lines) in Frontier Town. Plus, a big new ride at Cedar Point? That would get Gerstlauer noticed.
If not Cedar Fair, I could see Sea World possibly adding this to one of their parks since they are on a coaster-buying spree. Or maybe Herschend for Dollywood or Silver Dollar City. I don't see Six Flags buying such a large and expensive coaster, same goes for most of the small non chain parks as well. Very slim chance this goes to KI- I don't see us getting anything until 2023 at earliest. If this does end up going to KI this soon somehow, then it is likely gonna be The Vortex replacement- though opening a new coaster on a anniversary year seems unlikely, especially since CP didn't do that for their 150th.
