I asked the same question by email and got a reply.
"as far as we can see everyone who has paid within the first 7 days will be shipped in September/
October."
Not September delivery definitely maybe.
I have a preorder for a Saturn. Before checking out, I have sent them an email asking for the delivery date. I will post the answer (if any) in this thread.
24 hours later and no answer from KncMiner...
36 hours later, I have an incoming email from KNC:
Hi
The Miners are on schedule for September delivery and you can ask for a refund anytime up to the day of shipment.
