In the meantime, A3 are still available for ordering on the  Bitmain's site. What would we get guys when the second batch will completely be deployed?

Although all this stuff looks like a scam, just for fun but with the hope...
I placed an order and almost immediately  I got an email from their Escrow agent and I guess it is definitely an auto-reply. There was around 5:30 AM in Hong Kong when I got it.  Escrow's website looks like a real and has the physical address so I found a company who is the property manager and have sent a message for them just in case to double check do Escrow Agent is renting a real office in the building pointed in the address. I have a couple friends in Hong Kong so I probably would ask to visit the address in case the landlord will not answer.
