The front half of the park will obviously undergo an overhaul and retheme over the next two years. For 2026, there's not only the new Flying Fox coaster, but the restaurant (Casa Mia) at the front of the park is getting a massive overhaul. For 2027, the current 4D theater will be repurposed as an indoor coaster/dark ride that I've heard has yet to be chosen. The area around it will no doubt be overhauled - ala what they did with Discovery Cove. There's also a floating rumor that the giant swing ride (Skycatcher) may be relocated to the front half of the park.
I'm sure the focus will then turn to the back half of the park for 2028 and beyond. I have also heard that the park has been eyeing what to do with the rogue/poor placement of Kentucky Flyer. This is due to the fact that its often "missed" by guests who don't know how to find it, or even know its there. If the rumor of moving Sky Catcher to the front of the park holds true, that will leave it as the only dry ride in that back side of the park. It would also be the only attraction negating waterpark expansion into that land area. It will be interesting to see its eventual fate.
Finally, the Fairground's West Wing and West Wing Pavilion - adjacent to the park's entrance - are being demolished in the coming year or two. New wings are being built to replace them. That will affect the entire lot directly in front of the main entrance and will likely prompt a major overhaul to KK's entry plaza.
BTW - I was at the fairground this week and got to see the Flying Fox construction site up close. Probably only about 1/4 of the footers are poured. The station foundation is present, Once the park closes their Holiday event this week, I'm sure they will begin tearing up the midway for the underground tunnel. There's lots of prep work still left, so I'm sure it will be a month or two before any sort of track arrival/vertical construction will begin.
