Here's some things that would be nice.
-SGE removal & replacement Eventually, when Tomorrowland's overhaul is greenlit
-bring Indiana Jones Adventure to WDW Not as likely now, but still on the books as a replacement for the Indiana Jones Stunt Show if management decides not to update it
-Jiyi v.4 WDI will be handed over the lower pavilion (Journey into Imagination with Figment, Honey, I Shrunk the Audience and Figment's Place) soon. They already have free reign over Imageworks upstairs.
-updated Soarin' film To be made in conjunction with Tokyo's version if all goes according to plan
-Little Mermaid dark ride The construction bid was put out earlier this month--it has begun
-Pixar Place additions Soon to be announced
-updated RNRC Not anytime soon
- WoL getting big update Not anytime soon
-new UoE film Not anytime soon
-finished SSE descent Little by little, work will continue
-Sounds Dangerous removal & replacement Following the end of the Easter busy season, Sounds Dangerous will close once more. Pending any major spikes in attendance that are projected, it shouldn't be reopening. After seeing (or rather, hearing) the show for the first time, I am confident that the replacement will be far better received (by a specific audience). Not my taste, but it will do the job it needs to.
-Star Tours 2.0 On the way
-DAK expansion (Mysterious Island) Down the road
-Fantasyland expansion/refurb Begins with The Little Mermaid
-Toontown Remodel Not too soon
-Muppet's Studios Not anytime soon
-World Showcase additions Still up in the air
Any more ideas? I will add them onto the list.
