Hmm, I've still got 4 S3's in my shopping cart on the bitmain website... think the order would still go through?
No, it will show as sold out when you try to check out, but as soon as they open sales again you will be ready. Same thing here.
I bet right now they are working full crews to assemble the S3's for shipment. Hopefully the sales will open when they catch up. They must be shipping thousands of these next week.
