Speaking with Dengeki, Kingdom Hearts mastermind Tetsuya Nomura shared tidbits about Kingdom Hearts 3DS.
Sora and Riku are the main characters of Kingdom Hearts 3DS. Different from Kingdom Hearts: Birth by Sleep, Nomura wants players to use both characters while playing the game and is thinking about a two person switching system.
Nomura didn’t discuss the story, but revealed the game’s theme. It’s trust. More specifically, how to trust others.
