The Brick Pirate forum revealed today that we will be getting 18 minifigures in the coming Disney series. We typically get 16 minifigures per series, so this is a bit of a surprise. Rumor has it that Peter Pan and Captain Hook will be 2 of the 18 minifigures.
Some speculate that Mickey Mouse is also a very likely choice. Release date for the Disney Minifigures series is May of 2016.
