If Japan did get a final mix, I think it would only be what we got, and maybe 1 or 2 new commands/keyblades, but nothing over the top amazing that would make us all angry. However, I could see SE releasing a special edition, like the Platinum Edition for the first final mix, which a lot of extra stuff that even beats out the collector's edition. That would make me dissapointed...but thats about as far as I think SE would go to give Japan a Final Mix of the game.
