Square Enix has revealed the "Ultimate Pack" for Final Fantasy IV Complete Collection, the PSP release of Final Fantasy IV and The After Years, coming to Japan on March 24. This Square Enix E-Store exclusive is rather lovely to look at and comes with an artbook, game guide and 17-track audio CD, called "Final Fantasy IV The After Years Sounds Plus."
Five of the tracks on the CD have yet to be decided (Square Enix is asking Japanese Square Enix Members to vote for them from a list). Even if you aren't a member, you can still listen to samples of all the tracks in the running.
Final Fantasy IV Complete Collection, and the Ultimate Pack, have not been announced for release outside of Japan.
