If you ask me, the Horned King, angered at the fact that Disney has completely ignored him for the past 20 years, returns from the pit of the black cauldron and wreaks hell on the world. Afterwards, Captain Jack Sparrow and Peter Pan make out while Bagheera, Jaffar, and Rafiki ponder over how their characters are blatant racial stereotypes.
I also hope we get to see a conclusion to Barret and Donald Duck's rivalry, but I think that's just wishful thinking at this point.
I'm more interested in the love triangle between the animated brooms from Fantasia, Locke, and that half naked white haired chick from Atlantis.
Is it just me or does Disney have A LOT of IPs they haven't touched yet?
