For WDW I think anything less than an announcement of 3 ride additions or replacements would be considered a disappointment. Even that has the potential to be disappointing.
They could satisfy that with an off the shelf flat ride for Dinorama, a SSE redo and dusting off Mary Poppins.
I am preparing to be disappointed, but my (hopefully realistic) wishlist is as follows:
- SSE Update that doesn't include characters
- Imagination update that returns it to its former glory w/Dreamfinder
- Substantial overhaul to Dinorama with a net gain (over current operations) of at least 1 new attraction.
- Smaller updates like Harmonious, shows in DHS, etc.
They need to do more than that, but for me, Imagination and Dinorama are the big priorities right now.
