[SlipperySlope]

I agree with what you said, but I'm sorry you misunderstood my point. The ITRS lithography roadmaps for years have assumed that lithography would advance at the rate of 36 months between nodes, e.g. between 45nm and 32nm. But in response to AMD competition in the previous decade, Intel introduced their "tick-tock" cycle in which Intel advances the lithography node every 24 months. Other CPU fabricators have been forced to keep up with Intel's pace, and as you point out they have been a process generation behind.

As a result, 10nm will be released in 2015, rather than 2020 as ITRS predicted in much earlier roadmaps.

What gets real interesting in just a few years is how Intel and others will get below 10nm. Could be a shift to carbon based structures will be necessary.
