Historically, no Asic company has raised prices, even with products in hand. It's highly doubtful that the price will ever go up, since the return continuously goes down (even more so after shipping a crap ton of new hash to the network).
Are you sure?
The only company that never raised price was Asicminer.
Their products are overpriced, I never made the BTC back, but I am not even angry at them.
It was the risk I took and it was a fair bargain at that time.
Avalon and BFL like too raise price, but they can't do it now, because there are so many competition.
BTW Avalon is fucking cheap in China now if you know where to buy.
Already deployed a private farm in Fenggang, a small village near Shenzhen.
Even with the power hungry avalon Gen 2 chips it already earn the BTC back and will earn a lot more before Cointerra even starts to ship
