Just want to put out that they're not the first with this rumor. Alicia (and some others) revealed this far earlier than them lol
Universal is quick, they can get this thing done in 1.5-2 years, way before the rumored expiration date of 2028. There's been a lot of moving pieces for USF recently with timelines shifting around. Supposedly Simpsons has been pushed back a year or two to accommodate the Rockit project.
Rockit was unfortunately a byproduct of Universal grasping at straws to keep USF afloat while IOA got the bulk of the last few drops of cash the resort had prior to Potter/Comcast acquisition.
Considering the recent cuts throughout the resort... I believe the "multi-month refurb" between August and November is a cost control effort. It's the quiet season for USF with the park running HHN nearly every night, so really no need to keep F&F, a poorly attended attraction, open during that timeframe.
Excited for Epic, but boy it's exciting to know that USF is also getting a ridiculous amount of investment now.
2024 - DreamWorks, New Parade, New Nighttime Show
2025 - Possible Show in BMG Theater
2026/2027 - Rip Ride Rockit
2028+ - Pokemon/Simpsons
Edit: Universal just (or is finishing) work on two new HHN house locations backstage that will allow them to eventually remove the two tents closer to MIB/Springfield. (2 additional locations will be required however as the new parade required them to move out of the building)
