The Pace of Technology: Putting a Ceiling on Difficulty

Disclaimer: I am no expert and some or all of my assumptions may be completely incorrect. That is why I am here.
The current state of the art for mining ASICs is 28nm. If we look at past trends, this size is fairly difficult to push down and something smaller may not appear for the next two years or so.
The most efficient ASIC I can find is the A1 chip from coincraft. It offers 0.35 W/GH when undervolted. (Please comment the model and a lower ratio if you can find it.)
We can also set an average electricity cost of a conservative 10 cents USD/kWh. This assumption based on miners distributed around the globe.
The third and most important assumption due to volatility is the price of bitcoin. Let us put it at $600. A price of somewhat long-term stability and easy to use for calculations. Also, there is a positive feedback loop of miners selling their coins to cover expenses that keeps the price down. No one can predict the price, and it is the most important factor in this discussion.
I tried doing the math but it didn't work out - anyone care to take a stab at it? Basically, at this price, what is the difficulty ceiling where people simply cannot pay for power?
Cheers.
