I've given up understanding freedomno1 long ago...

After all, maybe it's not my English

I think FC only sold few hundreds blades. That's a totally out of nowhere guess without any fact backing it, but given the short time it took to sold out, my feeling is that it was rather limited. If that's the case, it was fun to see but won't have much impact on dividends.
In my opinion what is really important here, though, is the impact of seeing such prices, for other businesses. That's true for BFL because the maths are easy to do and everybody with a pre-order got screwed immediately (in case they still didn't get it until today...). But beyond that, a key point here is that it makes everybody wonder a bit more before choosing between (i) making a pre-order right now with many uncertainties, or (ii) wait and buy hardware from AM later, to get it
in hand just days later.
It has become obvious for everybody that AM is adjusting prices quickly and smartly. Many were shouting that AM was overpricing, but today we made a step further the road of realizing that as we get closer to the delivery time windows of some competitors (KnC first I think, maybe BitFury), the prices of AM will also get much more comparable with them. I'm curious to see the pricing of AM beginning of October: it is possible that all KnC customers get screwed like today's BFL ones with a single message of fc. Interesting times ahead, I'm happy to stand on this side!
