The second announcement from Marvelous is they have Luminous Arc 2: Will slated to come out on May 15 in Japan. Anyone who purchases the game early gets a Limited Arcs bundle, which consists of Luminous Works 2nd and the Luminous Symphony (read: CD soundtrack). The price is exactly the same, 5,040 yen with or without the items. So, if you’re planning on importing Luminous Arc 2: Will speed is your friend.
Speaking of Luminous Arc 2 I have a mini-pamphlet with a bunch of character art from both games. If you guys are interested I can scan it in or something. Just post a request in the comments so I know the work won't be in vain.
