Already has. Sadly, it's in Japan only. Just like they redid the first game in Japan only, and called it Final Mix, they did the same thing with the second one. Both times they add a lot of hidden content that the story can do without, but does make it make more sense and hint towards the plot of the next game. Well, when they made Kingdom Hearts 2 Final Mix, they also gave the buyers a PS2 version of CoM that looks pretty freaking amazing (especially if you think of how it must've looked on a GBA in 2d)
