Please check my math, tear my argument to pieces, come up with other ideas.. but try and help me answer this question. How the hell are we out of blades with how many we have sold?
I don't think AM is out of blades.
This is just supposition on my part, drawing inferences on how friedcat has behaved so far.
I think friedcat knew that the blades weren't a good deal for buyers anymore at 50
BTC so he pulled them and will either sell them in bulk in private at a discount or deploy them to keep the network share up (or a bit of both).
The alternative would have been to drop the price the public pays every time the difficulty went up. The problem with that is that it encourages people to hold off on purchases to wait for a bargain. I think friedcat is a smart enough businessman (smarter than basically everyone, heh) to know that mining is a classic repeat customer business. If you screw over your customers the way some other vendors are doing at the moment, they'll think twice about dealing with you again. However, if you under promise and over deliver, they'll beat a path to your door, again and again.
So he puts blades on sale for a while, then takes them off when they're no longer a good deal. People will learn that if they want AM products, it's best to get in early when the rewards are best, as they'll offer the best return early and won't be on sale forever.
In a few weeks, a refreshed product will come out at a lower price point with better features. Demand will have built up again, and early purchasers will have had a few weeks of less competition from other sales.
EDIT: Dimly recall from some marketing seminars that products are all about a "promise" - shinier hair, whiter teeth, attractive to the opposite sex, etc. Most other vendors doing pre-orders are selling a "gamble". AM is selling (relative) certainty. "Order this product today, have it in 5 days and start using it." That's a clear point of difference that no-one else has yet offered.
EDIT #2: That's also why I've noticed a lot of AM haters coming out of the woodwork. They look at the AM offering and scoff "how can you pay that much per Ghash? I can get xxx Ghash for $yyy from Company ZZZ. AM customers are all stupid." Those people are not in AM's target market (they really want a gamble, or they are possibly just self-deluded about when they will get their hardware) so they mock anyone who doesn't think the same way they do.
