Disney I believe has expressed interest in licensing things as they're recovering from Chapekavirus. This would be a good time for Universal to jump on that
I believe a big part of the 2028 push is not just to attract guests, but to add park capacity. The park also does still go through large patches of very slow season, time will tell if SNW remedies that. USH will absolutely not be getting a second park. There is no room and frankly, they still have expansion space in the current park that really needs work. Also LA is sure to see a tourism boom in 2028, and will likely synergise the hell out of the parks as Comcast is hosting the Olympics. Those two combined will help the park quite a bit I'm sure
