Disagree. Everything on that disney list will be open basically by the time JPRA opens. The only exceptions likely being Epcot Spine/SSE/Moana and Mary Poppins. But those should be done by spring 2022 for Epcot’s 40th.
Gate 3 certainly won’t be in that timeframe, and I don’t know what other project you think universal will have by late 2022, but they’d need to start in the next 6 months. They’ll likely have something, but I wouldn’t expect anything on the scale of JP or Hagrid’s.
WDW has a monstrous lineup the next 2.5 years. Epic Universe will be a thunderous answer to that.
I wouldn’t be surprised if Brazil and the AK expansion are planning to be part of the answer to that and announced around the same time Epic Universe releases it’s projected date.
What a time to be alive and healthy enough to ride everything!
Small sour note: that WDW lineup would’ve looked so much better with a MK theater and top notch show.
