Micechatter Brian Pinsky posted a great video he took in the Blue Sky Cellar. The CM in the video mentions some dates, and new developments regarding characters.
Information from after the 9:15 minute mark
Blue Sky Cellar-Fantasy Faire - YouTube
Fantasyland Theater opening in May,also stated as June, with the new Mickey and the Magical Map show.
Fantasy Faire opening in March, mid to late in the month, with new Meet and Greets.
-Princesses get permantent homes, sounds like they will no longer be randomly on the trails around the Castle
-In the new large meet and greet you meet, Aurora, Cinderella and Ariel(Little Mermaid mentioned), one after the other
-This new meet and greet will be open all day long
-Merida will move into the current Rapunzel M&G building inside Fantasyland, no timeline on this change
-Tiana will get a permanent home in New Orleands Square, no timeline on this change
-Snow White will be permanently at her wishing well on the trail on the east side of the Castle, no timeline on this change, but she is often there already so it may just continue
-Belle and the Beast will have a show then M&G after the show on the stage ends, stage is in the Fantasy Faire southern portion
-Repunzel and Flynn will also do a show and M&G like Belle and the Beast do
My reflection on this is, it's too bad these Princesses won't be on the Castle Paths as before, that was a great way to meet them.
