Were Bitsyncom in possession of 2+ million chips as of the end of June, with photographic proof including that of the Airway Bill and Tracking number  to substantiate such a claim?
Yes.

Isn't that your job - mail boy? Is there anything else you actually do for all the money you get paid by your customers? ... other than spend it in Vegas ...

According the TGB, there's one single big whale reseller supposedly ordered $14.75 million worth of chips and maybe even got an exclusive period to mine.  According to tracking data, they got theirs shipped on 6/25, 135 boxes full. Everyone else, especially the community who rallied around him at the beginning, seem to be getting the short end of the stick. 

you cant be completely right on both points.  if mining manufacturers are missing promised delivery dates then difficulty shouldn't be skyrocketing...   so someone somewhere is delivering their mining asics!

From my point of view, being more transparent here could only be beneficial for KnC with respect to their reputation and a kind of "shock and awe" for any competitor.

How long it takes to bring the ASICs to an PCB, debug all the related firmware and FPGA design on the linux daughter card, to have finally a working miner they can send to customers you can estimate yourself. But 2 weeks are not much time for that tasks.

Correct me if I'm wrong, but they can only refund customers with money they still have, can't they?

Depends on his goals/idealism... and how far he is willing to take it.

If Yifu Doesn't deliver them till the end of this month he shouldn't bother to deliver them at all.

oh man, all i want is to get my money back and then have some extra bitcoins to play with.
i hope, that is still/will be possible...

How fast do we have to pay if we won the auction

Hi, sent all chips and didn't keep a single one to check. Those receiving them will maybe soon be able to respond.
