Kingdom Hearts Birth by Sleep Final Mix hits retail tomorrow. Square Enix aired a final trailer at yesterday's 1st Production Department Premier event, and today made available an official version of the trailer for download.

The trailer and its background theme song are in English, but this is to be expected considering Final Mix is basically a Japanese release of the English Birth by Sleep. Final Mix adds a few new features, however, some of which can be seen in the trailer.

Square Enix says that the trailer has a glimpse at the new secret movie sequence that's been added to Final Mix. Can you spot it?

Joining the trailer, Square Enix shared a 15 second television commercial. View that at the official site or here:
