I know that most people believe that the two unannounced figures will be from a classic property, with Belle and Beast being the most popular opinion. Belle and Beast are certainly high on my list (I included them on my wish list post), but I think that the unannounced figures will most likely be from a new property. With that in mind, my guess is going to be
Red Riding Hood and the
Wolf from "Into The Woods". Why?
1. We all know that Disney likes to promote their new franchises first and foremost. Hiro, Baymax, and live-action Maleficent are getting figures. There's no reason why Into the Woods shouldn't.
2. These live-action characters do not have animation counterparts. There was a Red Riding Hood who appeared in a Three Little Pigs sequel, but she's a forgotten character that nobody misses. And the animated Big Bad Wolf is a Three Little Pigs character (and I think he deserves a figure at some point if Infinity lasts longer than 4.0).
3. Everyone's searching through what's already in the game for clues. Didn't we already learn from the whole Gravity Falls scenario that just because there's a lot of assets from a franchise, it still doesn't mean its figures are guaranteed. To my thinking, if the new figures are going to be patched in like everyone believes, then there's a good possibility that interiors, skies, and terrains can be patched in with the figures as well.
4. NOBODY expected Yondu and Falcon as the final Marvel characters. It's very possible that these two Disney figures will catch us off guard as well.
