With Kingdom Hearts 3D: Dream Drop Distance looming closer to its eventual Japanese release date, currently set for March 29, 2012, it has now been said by Tetsuya Nomura himself that because most of the game takes place in the World of Sleep, seven playable worlds must be awakened from the Realm of Sleep by Sora and Riku. As we know now, six of them have been revealed - Traverse Town, La Cité des Cloches, Prankster's Paradise, Country of the Musketeers, Symphony of Sorcery, a currently unnamed world based off of Tron: Legacy, and an unrevealed seventh world. Ah, seven does seem to be that most magical or lucky number, but... who's to say these are all the game's worlds? These are just the worlds locked away in sleep, waiting to be awakened. And what of this seventh world? What in the world could it be?
