It's best to contact Dezz directly. Look at the link at the top of the page, please.
BTW, Dezz told one part couln't get delivered before the holidays, but early January. It doesn't affect production much as this one can be placed on the boards subsequently. 20-25 cards can be produced till beginning of January. The PCB of the newer Switcher could also be ordered to be prepared by beginning of January only. But that one can be assembled fast.
ps. hush, there will be a little surprise for Christmas
