We've been seeing this from several sources and although not confirmed, the blueprints look very real. It could be that this is just one possible option out of several.
The expanded area remakes everything from where the current Little Mermaid meet and greet is, moves Dumbo, and goes back to the service road all the way across to the existing Toon Town Fair tents. The only attraction that will remain from the existing Toon Town is Goofy’s Barnstormer. Dumbo will now be located across from the Barnstormer and will be expanded to two spinners doubling the capacity of that popular attraction.
The rest of the expansion is dedicated almost entirely to the Pixie’s and Princesses that has become the marketing and merchandising focus of the Walt Disney Company the last few years. There are three new meet and greets Pixie Hollow is expanded, Cinderella gets a larger meet and greet, Princess Aurora (aka Sleeping Beauty) also gets a spot.
one disneyblog says the following "My thoughts on this plan? It’s exactly what I would expect Disney World to come up with as an answer to Universal’s Wizarding World of Harry Potter. Disney is essentially writing off the tween boys and focusing all their attention on the girls with the idea that moms and their daughters control the vacation purse strings."
