Okay here are my predictions.....some may not be announced but will happen eventually
Parks:
Epcot will be the main if not sole focus -
Updates - names and more info on: Spine project, Space restaurant, New land movie, GotG with I HOPE updated actual art for Spine renewal
New updates - more info on SSE redo and shut down, Water feature walk to and update of Seas(finding Dori?)
New - New name for FW area - I don't see how they can keep that moniker now and overall Epcot plan
WS - UK ride announced, Brazil Pavilion - yeah I think these two finally get announced.
I think this is going to be Disney's big push to hide the fact that Uni is building a 3rd park in Orlando...... by pre-launching NEW Epcot
Other adds:
MK - may or may not announce updates to Tomorrow land for 50th- Philharmagic, Orbiter, CoP and maybe Buzz
AK - I am not buying the new ride in AK or any major add. Only caveat here is primeval whirl....IF this is a real issue this may push up the redo of the Dino area that has long been rumored.
DHS - I think we get ONE add here to help this park more - Whether it be Black Box ride in VotLM or refurb of Rock n Roller coaster to some new IP. - also update on Mickey ride
I do think we get a blurb on DL Marvel area as well.
I also think we will get some kind of updates on new resorts - Reflections and Lighthouse probably
