Personally, I don't think that there will be a Final Mix for BBS. According to an interview I read, Nomura is already scaling up the difficulty level on the bossfights, and some other things are being given tweaks as well. That said, it would be so incredibly awesome if there was to be a FM version. In all honesty, I think a little more exposition would have been nice to have with the apprentices (Braig, Dilan, etc.) and perhaps even a cutscene or two describing them losing their hearts/becoming nobodies, etc. Actually, that could probably warrant a game of its own. Hummm...
