Funagain has the game in stock along with some other Japon Brand games. They have them at a premium price ($71 plus shipping) but I've bought from them in the past and had a pleasant experience. They do eventually clearance out stuff. I got a bunch of last years JB stuff pretty cheap. If you want to wait, the price may get more reasonable.
However, this game they might sell out on depending if AEG changes the artwork on their localization. I don't trust AEG to not re-theme this to the Tempest universe. We'll probably be escorting their Love Letter princess or something.
