Your best bet is to keep checking Yahoo Japan Auctions:

There currently aren't any copies for sale, but it does show up there. There are a few other Japanese sites that do carry it, but none that of them is as easilly accessible to Westerners, so you might be stuck with waiting for it to show up on YJA.
