intel and Nvidia are definitely already pressing 14nm tech... and AMD is moving out of 22nm now and starting to work at the 14nm level. This means there is not a single SHA256d ASIC developer out there that could get production time anytime soon. At BEST, someone will eventually get in the abandoned 22nm line when INTEL, AMD and Nvidia have all moved the majority of their product to the new 14nm on a solid basis.

What does this mean for us miners? It means you will see one more "double down" in ASIC efficiency in the next 18 months which will kill off 65nm and 55nm miners completely. Look at it this way...

1. 65nm BFL chips are turning LESS than 2 cents per day per GH/s at $.10 per kWh at 5-6 J/GH/s
2. 55nm Bitmain chips are turning LESS than 2.5 cents per day per GH/s at $.10 per kWh at 2+ J/GH/s
3. 28nm HF Habaneros are turning LESS than 2.6 cents per day per GH/s ay $.10 per kWh at 1 J/GH/s

Nothing that I have seen (that I believe anyways) has proven to really mine below the 1 J/GH/s mark yet... that can be had by consumers at this point. I won't believe the Monarch figures until someone third party verifies it in their own hands. The odds of us seeing a 22nm product that is double the efficiency of these 28nm products is laughably impossible. Not until 14nm ASICs will we see a double down from these Habaneros and other 28nm miners. The time and funds it is going to take to develop 22nm would almost be for naught except it is going to be the second halving before anyone can say they have a 14nm chip lined up at the foundry.

Put all that together and you should see, by the end of the year, a price increase in BTC, a plateau in difficulty... and people ditching their old gear for 28nm as quickly as the vendors can stock the miners... all of which should enable a Habanero to ROI this year.

If anyone disagrees or has anything to add or clarify on the above... i welcome feedback.

Pretty sure it's not optimized for the 58XX or 59XX series.
