Well that was a bit disappointing. The free promo CD I got from my trip in compensation for Uematsu not being in attendance is merely a sampler of songs from their corresponding soundtracks. No special orchestration or arrangements. Oh well; at least now I have something "official" for Bastok, Windurst and Blinded By Light now.
On an unrelated note, Steam updated the store page for FFIX to include the official trailer as well as the updated ESRB listing to now include:
Violence, Blood, Suggestive Themes, Partial Nudity, Mild Language, and Crude Humor.
