I think eventually we will see more dark rides in our Fantasyland. There is still so much room for expansion, especially if they get rid of Autopia. I really think this is more like Phase I out of III.
After the mine cars are open, I have a very strong feeling we will see Pan go down for a year or two for a near-complete gut/rebuild. It needs it terribly - every single set needs a lot of work, and to become ADA-compliant the entire ride system needs to be replaced (which I hear is needed anyway as it's simply ancient at this point). They just couldn't do it before because of the lack of Fantasyland attractions, but with TLM and a new Snow White ride, it will be a lot easier to justify. From there, IASW will probably get the character overlay that Disneyland got (which is subtle yet fantastic), and perhaps something to plus up poor old Pooh.
But after that...apparently there is room behind the B&TB area to work with, and of course Autopia, the ride without a land. It doesn't fit in Tomorrowland, it doesn't fit in Fantasyland, and although many people have nostalgic memories of it, there is nothing it offers that your standard antique car ride at your local amusement park doesn't. And it takes up a HUGE plot of land.
When that's done, I'd love to see Pinocchio and Alice brought in, and maybe even a 3rd one - Sleeping Beauty would be amazing. WDW is the flagship park, yet we have always had the worst Fantasyland. I mean, walking between Tomorrowland and Fantasyland it was/is hard telling where the line between them is - and not in a good, "ease you into it" way. Our Fantasyland previously consisted of a bunch of tin-roof "King Arthur" tents and a few scattered trees, and felt pretty cold/lifeless. I mean, Tomorrowland has more personality, when Fantasyland should be the heart and soul of the park.
I can dream.
