Honestly, at least for the next few seasons, I would expect not much more being spent on new rides but maybe some flats; I would expect more aesthetic improvements like removing the rest of the blacktop from the midways, refurbishing/restoring various buildings, and perhaps re-establishing or refreshing theming.
If FoF were to close permanently, the big question is if/when they'd want to spend the $ on demolition. It'll be interesting if they choose to leave the building or not, and if they want to go through the expense of busting up the concrete.
Personally, as far as rides are concerned, I'd like to see Soak City get a bunch of infill and/or slide replacements. Either repurpose Action Theater somehow, or convert it to a modern dark ride. Do something with the sky coaster, go karts, and Dinosaurs Alive plots. Remove the fencing next to Pantherian and where Anaconda's station used to be to at least get a good view of Lake Charles.
