I think expansions/investments like SWGE will be avoided for a while, and stuff like Frozen Ever After/shoehorned projects will occur over the next few years. I hate being pessimistic, but I don't see a major expansion at any of the WDW parks opening until 2030 at the earliest (unless Disney literally changes their mindset).
MK - something at Stitch
EP - Imagination Pavilion, I think the rumored Epcot hotel will convince them to finally work on this
DHS -Theater Show replacements with more relevant IPs and maybe an attraction taking over Launch Bay
DAK - other than Dinoland's reimagining, the only other project I see happening before 2030 is a nighttime show.
