This game just came out for PS Vita and PS3 in Japan on March 26th, and the accompanying soundtrack was included with the Limited Edition version of the game.
I am hopeful that someone eventually gets the soundtrack. If I had the money right now, I'd grab the limited edition version of the game, but according to Play-Asia, it'll cost $150 CAD for me to obtain. Just a little beyond my price point, unfortunately.
