I’ve been thinking about this for a little while now. Here’s my logic. Most everything in this park is going to get scrapped/become parts donors. Just going down the list of rides and what could be done:
Batwing—unless someone is willing to put up with the insanity that is a Flying Dutchman, this will likely end up being scrapped.
Superman—they just got new trains, and relocating this seems rather unlikely. I’d be willing to bet these trains go to Darien Lake for their Superman.
Starflyer, flying scooters, Harley Quinn, maybe riddler—relocated or parts (I find riddler more likely to be parts donor than relocation)
JJ—park not within the SF chain buys and relocates it. If not, parts donor for Poltergeist.
Penguin Blizzard is likely to be scrapped. Only one in the US if I remember correctly.
Wild One—ride unfortunately is likely dead. Maybe Knoebels steps in for this one? If not, trains probably get set to another ride in the chain, they’ve got quite a few that could utilize them.
Ragin Cajun—the most likely relocation coaster, given the portable nature. If not, definitely becoming a part donor.
Roar—this can die. No one really enjoyed it. But trains could be sent to Predator at Darien Lake.
Firebird— this is an interesting one since it’s the first B&M and somehow has outlived a couple others at this point. Most likely the ride is scrapped but trains become part donors. Maybe for Dominator by chance?
Skywinder—kind of a wild card. Could be relocated, or axed for parts donor. I know SFDK has been working on their SLC, maybe trains go to SFDK, the rest of the ride is parts donor? If relocated it’s more likely to be outside of the chain.
NebulaZ—I feel confident in saying this will be a relocation. The ride is practically brand new still. Various other flats I find likely to just be relocated or as parts donors, river rapids and shoot the chute are probably dead.
