I have some strong rumors from wdwmagic these things will happen over the course of the next year according to the source.
AP prices will go up again, Disney is looking to dump their current ticket provider Omni-Ticket because they were acquired by another company. They are likely to just use their internal ticketing system. They may start to replicate the
Disneyland AP tickets and turn it more into a membership program that can automatically be renewed yearly or even monthly.
Dining hours at resort bars will change most likely similar to how disneylands is. This is mainly because trader Sams is coming and needs to be successful.
Fences will continue to go up around pools at the resorts.
New magic bands will be coming out, Disney wants to sell these things like crazy. So new designs. Disney is also expected is partner with apple on the apple watch for that to be used as your magic band as soon as apple lets developers use NFC for something other than Apple Pay.
Epcot is still only getting frozen and Soarin third theater they don't want to spend money there just yet.
