My order was placed on 8/31 in USD - payment was not confirmed until 9/10 - power supplies shipped shortly after that and the order showed as shipped.  I just searched my address on UPS and have discovered that the S7's appear to be coming by end of day 10/14.  No additional shipping notice from bitmain.  I did receive a shipping notice when the PSUs shipped - it seems as though their system doesn't really support backorders - I wonder if there is no subsequent shipping notice because their system thinks it is already shipped?

At any rate, they will be a bit late according to their promise, and quite a bit later than I hoped they would be, but I'll be glad to get them up and running.
