I don't know if this might help anyone, but I had some CDjapan points that were due to expire on January 1st, so I wasn't going to be able to use them for the Spartan release.
However, a couple of days ago, I tried to order a Wave Macross model, which the site said was available at the supplier.
Today, I got an e-mail stating that my order was cancelled as the item is unobtainable.
The good news is, the CDjapan points were returned, but have a new deadline of one year from now, meaning I can use my points for the Spartan after all!
