I think you have Dreamworks, which is a major upgrade to this area of the park, likely adding food items which only help make $.
Likely, and rumored, a new parade and nighttime show. Those are major additions to a day at USF. Add in this is the special events park, so there’s always a “reason” to visit.
2026, I hope JPRA becomes Jurassic World. 2027 seems rumored for Zelda.
That leaves 2028 open. The trend of family focused properties is noticeable, so a dark ride added to kidzone would be another great addition.
2029, I suspect an Epic addition, so this would lead to nothing new for USF till 2030.
I think it’ll take a few years for USF to catch-up once Epic opens, but they’re making smart longterm additions right now.
