It takes place after Re:Coded and follows Sora's and Riku's Mark of Mastery Exam. Besides that, not much more is known about it. But I read on Kingdom Hearts wikia that "Nomura has said in an interview that these scenes are not from the actual game, but rather, "The trailer merely portrayed the overall feeling of the game." ". Don't know how factual that is, but if so, then the trailer may have only had them appear like that for now, but they will be in their KH2 outfits in the actual release. Y'know how some games in the early stages make vast changes to characters appearances? I'm thinking it's something like that.
