Well, I guess starting a new batch of preorders and going offline/silent shortly after with open questions from customers might be an answer in itself...
give them a break. After making a turnover of around 700.000 $ in a couple of hours, they probably opened a bottle of champagne (or Appenzeller) or two, and at this time just slowly start to creep out of their beds with heads like ballons.
Ahhahahaah

Appenzeller is supposed to be a cheese, not an alcoholic drink to party with

You should also consider the time zone....
Yes please, me & chris have been answering the phone till 3 am yesterday, then we got to stop answering because at 8 am I had to go to the PCB factory to discuss the new production timeline for the 2nd batch... not really that easy to answer to so many questions from so many users, sorry about that we try our best (and I think we're doing pretty good considering that the feedback you get from other mining vendors is close to zero).
I prefer to buy real machines with real gigahashes .. now ..
Can you (all the People with preorders, in the 3rd row too) imagine what is happen when no (nada, zero) chip will be delivered to all the "mega-giga-hash-rig-supplier" ?
No one of this "mega-giga-hash-rig-supplier" can refund you!
Then it will be a little bit quiter then .. enjoy the hum of my real-existing-rig

Don't worry about that, we are working on plan B already should this ever happen, even if it's very unlikely as Avalon has got a very good reputation and has no reason for not producing a couple more of their already-existing-and-working ASICs from the foundry.
Nobody in the office? A fried of mine was trying to give you a call...
Sorry probably we have been busy on the phone already, try to call again tomorrow morning and please mind the timezone (CET).
