I think the park will be sold and most likely to an investment buyer. They will then slash the budgets and operate a roller coaster park and we will all become in-park archeologists reminiscing about the old days.
Imagine yourself in 10 years taking a (now rare) trip the Busch Gardens to ride the new Hyper Bomb™ coaster. You enter through what used to be England, and take note of where you can sort of still see the signage for Squire's. There's still a hamburger thing in there, of course, and you can kind of see a young teenager in a baggy polo picking at their hair behind the counter. You proceed onward through Ireland, stopping to notice the old talking tree (which still tells tales of Corkscrew Hill...although that simulator has been shuttered since 2013). The bark is eroding...you can see the hard-shell foam that makes up its interior exposed over the left eye. Passing by what is still, by name, the Abbey Stone, you see the faint outline of showtimes on the chalk board. They're for shows 2 years ago. You pass through the Wild Reserve; past the empty aviary and abandoned animal enclosures. Into Aquitaine now and you see the trappings for sale in the French shops: crazy hats. Licensed memorabilia. Keychains with names on them. Across to New France now, where smells from "The Smokehouse" are wafting into the air -- the smells of pizza and hamburgers identical to those sold in the former Squire's Grille. Through New France and finally into what is ostensibly Germany: site of the bright green Hyper Bomb™ double-winged blaster coaster. You can see the towering ride clearly through the "Germany" giftshop. You notice that the merchandise here is the same as what was offered in the French shops...with the addition of some plush items from a recent animated release and some items from popular teen clothing brands. Standing in front of the queue turnstiles for the Hyper Bomb™, you notice in the distance the spire of DarKastle...the paint of which has now faded so that the "shingles" match the "stone" of the castle's facade...and beyond that, in the far corner, you can just make out the weathering on a cream colored, Bavarian-looking building; the patterns of which create a clear labelscar that reads "Festhaus" almost as clearly as the bright blue lettering once did.
