I was talking about the PR pictures they posted a while ago, like this one:
http://i.snag.gy/WE5Kk.jpgThis is also the inside of the "bigger one".
There were doubts if that was a shipping warehouse or a mining farm because there are no cables or any other infrastructure except miners on shelves. To which the CEO responded that this is indeed a mining farm nearing full capacity and the last few shelves of miners were chosen for the photo shoot right before they were plugged in. I'm paraphrasing here because I think the original post was eaten by hashtalk migration. So it feels a bit like a time machine trick to see a transformer pad still under construction and the interior still being furnished. Either these new pictures are old or those old pictures are not a functioning mining farm. Probably the latter, because there is some cabling and ducting in the new pictures.
This looks like the same building, but the miners are gone. They said there are 3 data centers, so it's possible they were using one of the warehouses to store the hardware while preparing the other.
The miners shown on that "PR" photo may be already working in a different location.
Anyway it doesn't look like they're packing their bags and running as some people suggested. The CEO was asking on hashtalk for best data center locations, so they are planning to expand even further.
I agree, there might a plausible explanation for all this, they're just not making it easy with those announcements etc. For example maybe the hashlet was - at least in part - a pre-order to fill up that warehouse slash mining farm. Which would explain the hesitation to publish mining proof/stats and the new ductwork and perhaps even the Vaultbreaker to some extent.
