My only concern from watching the trailers is that the game will pull another FFX/XIII and not really open up until the end game with the rest of the game being told in set pieces that will drive you forward. KH pretty much does this so I'm kind of expecting the flow to be similar. Wouldn't be surprised if they did away with the world map or exploration in general, though said set pieces will probably be large though easy to fully explore in a first run.
