Of course, Intel is already working on the nest step, 14 nm, and expect to be ready in 2013, as it is already in development. Beyond 2015, Intel is already foreseeing, 10, 7 and even 5 nm engraving:

In fact, Intel would initiate works on an engraving process about 10 years before it enters full production mode. With such communication, it becomes more and more obvious that Intel has a huge technology advantage with its competitors, beyond the engraving process itself. In the coming years, if AMD and other founders do not react efficiently, it will become more and more difficult to catch up with Intel... Maybe, it is already too late?
