It's out! According to Namco Bandai's site, anyway...

Anyone manage to get the music yet?

You can find the soundtrack for Eternal Sonata in this link.

Enjoy.

Not quite. There's a few tracks in the PS3 version of the game (for instance, the background of the Mirror's Lament dungeon) that are newly-added from the 360 version.
