These seem like good projects to me. But it shows the pending folly of our three park ecosystem. 3/5 of our unknown project years (2028-32) you have assigned three Epic dark rides.
That doesn't leave much wiggle room for the other two parks. Assuming, optimistically, Universal keeps up the one notable attraction a year cycle.
My timeline on that specific Epic plan is ambitious and likely unrealistic.
I fully believe the next 5-10 years should be USF's golden decade with major new additions and aesthetic overhauls. A more realistic timeline, when considering the other two parks below.
Universal had a period where Transformers, Springfield expansion, Skull Island, Cabana Bay and Diagon Alley were all under construction simultaneously. With other major projects like Volcano Bay, Sapphire Falls, Fallon, and Supercharged all under development and nearing the start of construction.
*I am missing projects, and stuff like Figment & Space Mountain are just wild guesses.
USF - Prioritize a replacement for Fast and Furious immediately for short-term gain (BTTF), open up the Rockit replacement, and then a major addition (that is primarily physical environments) with Pokémon. The park also needs to improve its guest experience with major aesthetic overhauls of certain areas (mainly the park entrance & Minion Land)
IOA - Add Wicked to Lost Continent, bringing use to a deserted area
and more importantly, adding an entertainment component to a park devoid of live entertainment.
UEU - Prioritize smaller capacity additions, with a major family-friendly dark ride in the next 3-4 years. (I'd personally make a Dark Universe addition first, but likely Nintendo sees the expansion first.)
I hate saying this, but if Universal can do smaller capacity additions to Epic Universe and just one family-friendly dark ride... they can justify not expanding that park until the next decade. I hope I'm wrong.
