Not sure EETimes attended the same papers I attended. I heard both papers, and spoke with several colleaggue. The consensus was universal: all believed in the Semiconductor Engineering version (link above). The papers were anything but a revival.
I haven't seen good cost estimates but that is actually my primary area of experitise these days. I am currently working with several lithography and materials experts on detailed comparisons of all of the alternatives.
I can say that Intel has detailed plans through 10nm and they are forecasting that their cost per die is going to continue to go down ~30% for each of the 14nm and 10nm nodes. Intel is a little bit unique at the moment in that they are doing a full srink at 14nm where many foundries are maintaing the same BEOL for 14/16nm that they have at 20nm
