Up on Amazon JP and dominating the bestseller lists. Seems BFB and Mirai House haven't worked out selling through Amazon itself yet, so there's no international shipping just yet.
(No tank, presumably the last minute decision to change the color has something to do with that.)
(Also no group listing, but BFB's still been vague on if there's anything special about the group listing, or it it just means they'll ship the four individual releases to you all at once.)
