It seems like this is just an engineering setback which was a risk that we took with pre-orders. If it was a straight up scam, then these people would be gone now with our money. The only "scam" I could see right now would be minersource keeping the hardware for themselves when it comes in and I don't think that is going to happen (besides PG will be all over them! LOL).
I am frustrated with minersource's lack of communication though. I emailed about my 3 x-1's in their old order database (batch 1) about a week ago and still no response.
