I think it should be simply a price that maximizes profit. Selling more for a lower price or selling less for a higher price. Something in between. Asicminer cant change the buyers behaviour. If they dont buy here they buy elsewhere. And it doesnt matter how much preorders are floating around. Thats something the buyers seems not to consider.
To maximize profit is to set the price (at least) as high as possible for the product to still be selling in whatever volume is being produced.
I'm a genius.
