Dont blame the asic manufacturers. Its the miners demand that creates these prices.
But this situation was entirely predictable and predicted. Even if an asic manufacturer tomorrow starts selling asics at $1/GH, its very unlikely miners will make a profit. THe lower price will just result in higher volume, and thus higher difficulty and all those miners will be equally screwed once the asic price drops further, which it will once demand slow down. This is a race to the bottom, and for 28nm that bottom lays somewhere close to $0.1/GH and depending on electricity cost and efficiency,  a resulting network hashrate >100PH. Overall miners will lose every step of the way down there.
