I don't know where you got that from, do you have any sources? The 2009 edition ITRS concluded that there's no significant remaining roadblocks for 22nm processes. They listed some challenges for 16nm but they do expect to overcome all these obstacles in time to keep Moore's law going for at least another 5 years. No manufacturer that I know of have said that 22nm is going to be a limit. In fact Taiwanese researchers have already produced a 16nm SRAM chip in Dec 2009: http://www.taiwantoday.tw/ct.asp?xitem=87144&CtNode=416 http://www.taiwantoday.tw/ct.asp?xitem=87144&CtNode=416

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.
