Is that a serious question?
They will announce nothing....just more fantasyland, fantasyland, fantasyland dead horse beating...
On another note: I do believe we've seen the last of the anniversary promotions as we knew it from the pink castle days.
If i were a PR hound...and i'm just guessing here...then the anniversary and birthday ideas are too limited in scope for what they want to do going forward. They don't want their "celebrations" tied to a calendar year period because they want the flexibility to make them as long as possible and schlep more merchandise without changing logos too often (tough to reset those screen printing and stitching machines...especially if you can't speak mandarin and don't understand the labels printed on them

)
It pretty clear that with the "magical gatherings", "Year of a million dreams", "what will you celebrate?" things that have rolled through in the last ten years that we are going to get repeats of the same ideas over and over again - using disney's pedantic arsenal of buzz words to attempt and get the same thing: more people coming back more with more money for stuff.
