I'm really curious to see how Square implements Sora traveling to "worlds" in KH4. If Quadratum is a reality where light and darkness do not exist, then the world itself wasn't splintered into different pieces like it was in Sora's reality. Which would make Gummi Ships pointless. I'm guessing it could be like KHUX where Daybreak Town acted as the "hub" world for the game and Sora travels to parts of the world by opening up a portal with his Keyblade? What do you guys think?
