I'm amazed how many people got dollar signs in their eyes and threw money at a company who produces vaporware, run by a known criminal. Personally I would never pay 100% of a products cost upfront for a preorder with no guarantee it will ever show up at my door. I might pay 10% to be put on a list and pay the rest when the unit is ready to be shipped.
My guess is that BFL is mining the crap out of all their machines right now and that they will ship them when the profitability is almost zero. Like other people on this forum have stated, why sell their money printing machines?
