With the D23 Expo next year, makes you wonder if they'll hold their cards close to their chest until then, or announce to draw more people to come to the Expo to see the concept art and models.
After the anger they got last year from having nothing at all to announce, I think it's pretty safe to say there will be announcements at D23 next summer.
I've already been told to expect some major Shanghai details and not to be surprised if a major DL announcement (on something that will likely already be under construction) is also made. Where this WDW news comes in, I really don't know.
If Disney is afraid that people will feel any news will overshadow the modest Fantasyland project and postpone trips, I think they're sadly mistaken. They need some real positive buzz that transcends the fan community and they don't have it.
