@Neptune: Did some research about Hamauzu being the composer; sadly, I couldn't find much save this tweet by someone random:

...and I'm not really sure if I trust it. However, the track on the official site does retain his ambient and piano melodies, not to mention the orchestrated "battle" tunes which, after Blinded by Light, Fighting Fate and Nascent Requiem, I've come to expect from him. Certainly, the beginning part of the track on the official site reminds me of "The Thirteenth Day", just made much better.
Otherwise, even if it's not Masashi Hamauzu, I still anticipate whoever managed to create the track on the site. And I am looking forward to the game, actually. \o/

EDIT: Also, for those who want to listen to the track on the site without the URL hogging up your tab space or so...

Extracted out and uploaded for your enjoyment. Not sure if I'll get banned for this or reported but...oh well. For the sake of good music, I'll do it.
Apologies for anybody in countries which cannot access mediafire.
