As far as expansion in this park is concerned, I am waiting to see if the TSMM ride expansion actually starts to happen come October. To me, this would become a necessity if they are phasing out other rides in the area. If this doesn't show signs of happening on October, then this area could sit for some time. At the pace that WDW builds attractions, they are obviously never in any real rush.
I have noticed posters casting lines out to our trusty insiders to see if any of this massive park expansion is actually happening. I know that at one point,
@Lee simply replied "they are", or something along those lines regarding building new attractions. It might have been in one of the other threads.
I only believe that this is happening, only if for no other reason that Spirit, Lee, Jim Hill (I know) and others have spoken of this now. I just think that at WDW's glacial pace, it is going to take time. Also, I don't see a massive construction project at DHS starting up in earnest along with everything going on in DAK, DS, the hub at MK, Poly and where ever else.
Looking at WDW as one massive resort complex, I think this will fall in line as follows:
1. FL expansion
2. DS total overhaul
3. DVC, MM+, hub at MK
4. DAK and EPCOT Frozen
5. DHS
As far as EPCOT goes, I am not entirely certain what the future plan is for this park. It seems that as far as WS is concerned, I don't see them adding any new countries. TDO seems content to use this as the festival area for the WDW resort. Maybe the plan on piecemealing rides in here or there (i.e., Frozen). FW though, aside from the possible Soarin' expansion and plussing, is the one area that I throw my hands up in the air. I simply don't have any opinion right now as to what they are doing other than repainting it. Maybe the attendance figures keep them from really doing any major refurbishments to this park.
This will then have most of the parks, DVC expansion/transformation and DS projects finished by 2021 - 50 year anniversary for WDW. Add in new FoF parade, new fireworks for MK (thank you Pandora jewelry) and maybe EPCOT (Steve Davison?) as well as 1000 more up charge events. To me 2021 is the finish line of a long marathon for TDO. The problem is we wish it would only be a hard run 5K instead.
