I said it will get difficult below 22nm, not that 22nm was itself a limit. Moore's law isn't going to end at a discrete point. What will happen is that each generation will become progressively more difficult to put into production, until alternatives like 3d integration are more practical. We're already seeing some of that with 45nm and 32nm, but sub-22nm is going to be very challenging. My source is also the ITRS.
