That might not last as long as you think. Apparently Global Foundries thinks it can reach parity with FinFET 14 nm chips in 2014, which is Intel's (new) timeline as well. I think this is happening because of 2 reasons: Intel has experienced delays of a few months with every latest generation, and GloFo also found a shortcut to the 14nm process:

"By moving to 14nm finfet while keeping 20nm interconnect, GF has brought forward the introduction of its 14nm process by one year."
