I understand the mfg are in it for profit, and many have kept a reasonable price. The difference is now they cannot make as much of a margin per unit. I am curious if they are selling near their mfg cost or if they have room to go down farther. or perhaps a new product will be necessary to make it more profitable for the home miner. or if home mining is now completely dead and most mining will be completed by mfg. maybe that was the plan from the beginning, use the sales to build capital and then use the mfg capacity to expand long term mining investment.
Manufacturers could theoretically give away mining gear for free but with the rising difficulty and the relative inefficiency of the ASICs currently in production, it will be very soon that you won't be able to cover your electricity costs with the BTC earned. In fact, some people with high electric costs have quit already.
