I'm waiting for the announcement and proof that they have working prototypes hashing at X GH/s and using Y watts. If they can demonstrate a good product at a good price, I'll consider buying. Otherwise no.
you know that is impossible.
if there is 100% working product it can only stay on the shelf with ASICminer prices, or sell out in seconds
that is why the gamble on pre-orders brings the price closer to normal ROI. it is left up to you to drop your cost-basis as much as you can so you can profit against others doing the same
