The boards look legit; or at least, they look very much how I'd expect a board to look, given the power demands for the claimed ASICs; and is consistent with the previously shown PCB layout images, and

Interestingly, rather than design their own voltage regulators, they have gone with pre-packaged modules (the big rectangular modules along the top). Probably sensible, given that building high power VRMs is a bit of a black art.

That said, if their wafers are finished, then they must have taped-out when they said they were taping-out (the July update) as 2 months is the shortest realistic time frame from tape-out finishing to wafers going for processing.

Based on other manufacturers experience, it takes about 1 1/2 weeks from wafer completion, to chips "in hand". From there, you should allow 4 weeks for assembly, testing, tuning, firmware tweaks, before shipping, and that's optimistic. KNC sent their titan wafers for cutting and encapsulation in early August. They shipped in last week of September, but early results have not been good - huge numbers of DOA miners, firmware incompatible with multipools, and loads of stability problems.
