The new world will help pull in the younger crowd, as more likely worlds for KH 3 could be the following;
-Big Hero 6 (to have the Marvel side of Disney covered)
-Tangled, Frozen and Princes & The Frog (to cover the younger fans of Disney and represent more recent films)
-Wreck-It Ralph (to cover the gamer demographic or older kids)
-Star Wars Episode IV (to cover all demographic's; older fans who grew up with Star Wars, newer fans of the upcoming film, and younger fans who loved the Star Wars cartoons)
That should cover all the bases for Disney

. That alongside bringing back two or four worlds from past games (PoTC for the second/third movie, Lion King for the second film, Fantasa to represent the original film, and Olympus Colusem to cover exploring Mount Olympus, something never done in prior games in the series) and new worlds based on older Disney films (Treasure Planet, Atlantis the Lost Empire, Emperors New Grove, Rescuers Down Under, Sword and The Stone, Pocahontas) and you have a killer set of worlds for KH3
