Basically just an international version that all FF titles seem to get although, they announced this far earlier than what they usually do.

Square Enix have opened a teaser site for Dissidia Final Fantasy: Universal Tuning scheduled to come out on November 1. As expected Dissidia Final Fantasy: Universal Tuning is an “international” version of Dissidia: Final Fantasy . The revised game includes the arcade mode Square Enix added for the Western release, over 100 extra character tuning options, and English voice acting with Japanese subtitles.
Dissidia Final Fantasy: Universal Tuning will be released as a retail game and a downloadble title on the PlayStation Store. Previous save data (i.e. save data from the Japanese verison) can be transferred to Universal Tuning.
