Well it was a bubble that couldn't last forever (Kid)
It's just a temporary reprieve after all economics does play a role in unit costs etc, we will need to wait for newer units to come online into the market which offer more GH / Cost or for the market to react and people to start mining because its stable.
Anyways this was expected
Going with Chris and his comment in the article
The changes from CPU->GPU->ASIC were events that disrupted the ecosystem due to decreased predictability of hash rates in weeks, months, or even a year and as one nears the end of a huge transition period, this will happen. When you have a level of stability (e.g. 1-2% increases vs 20-30%) it makes it easier for anyone to mine because getting a miner a month or two late won't significantly change the profitability (or lack thereof) of mining hardware
