2028 feels a little ambitious for Potter, the ride hasn't started construction yet. I think the Supercharged replacement will be that year instead. It's an (almost) brand new building in the middle of the park on the way to the most popular area in the park. I don't think they'll leave the building standing there for years. I can see it being a budget project though.
2027 - Hollywood Drift
2028 - Supercharged Replacement
2029 - Pokemon in Lost Continent, Dark Universe expansion
2030 - Wizarding World Paris expansion
After that I think we'll get a break. That's a ton of investment into the parks in a short amount of time, especially after just opening a brand new park.
