So reading between the lines and jumping to conclusions it sounds like Disney buys rights to Sesame Street, takes over Sesame Place and then moves MV3D to the park in PA. I then become the creepy middle aged guy with no young kids who has a season pass to Sesame Place
Getting back on topic….it could be a little sooner. If we assume that Villians land opens somewhere around 2030 or 2031 then the “next thing” to open could be whatever goes to AC. There is no guarantee they plan it to open the very next year but if they plan to spend the money they announced and spend it in a decade it would have to open sooner than a decade from now (the decade would end in 2034). If you add up all of the spend announced for all the parks and cruise ships there’s still plenty left over for more stuff before 2034. Also no guarantee it goes to WDW but they will likely get some allocation of funds.
I personally would prioritize a new land in AK to expand capacity there but AC would be plan 1b for me with EPCOT a close 3rd (WoL, imagination redo, new country, etc…).
