One thing that I remember is that Iger stated that the big expenditures for WDW would not start until the latter half of this decade in one of his conferences. So, they might not start anything, i.e., shovels in dirt, until 2027 or 2028. I'm guessing that they are betting on a) Their fans won't go to Epic, b) A rising tide lifts all boats (more visitors for both UNI and WDW, or c) Weather the Epic storm and then strike after it cools a little.
I have no inside opinions but Disney could be in a for rude awakening, as happened with Potter. I also wonder if their actuaries or whoever is doing the predicting are feeding upper management with rainbow-colored visions of the future.
