Uni is making a ton of money keeping guests on property. That is why they are reviving dead rides and add capacity, to put butts on ride seats who stay in hotels and spent.
Jaws was one ride and some carnival games (moved to Simpsons), now it's 1,5 rides, an interactive game, shows, interactive shows (bus, wand), shops and restaurants.
Twister transformed into an 20 minute experience incl shows, museum like area, lounge area, interactive games and a shop.
Kong, unused land, Transformers, unused area, Raptor Encounter, unused land, Volcano bay, unused land.
At the moment we get a huge plot of land replacing Dragon Challenge and I'm sure more people and a wider demographic will use that land and it's attraction(s). I see Disaster replacement as Fallon, underused ride (like Jaws beyond repair) adding more fun time and a ride that eats people. The same will go for Nintendo and the Terminator replacement.
