I think it's hard to say if the closing of SFA will impact SFDL. Could we get a coaster from them, maybe. The thing is that none of their coasters was considered great. Maybe the Premier spaghetti bowl or one of the kids coasters.
They also only had a few flat rides that would work at DL. Further complicating things is that they may not want to put these rides into parks they don't own.
Honestly I see some of the water rides and slides as possibilities to come here, if anything
