If Intel remain on track they will be shifting from their current 32nm process introduced in Q4 2009 to the new 22nm in Q4 2011.
After 22nm, in Q4 2013 the company are set to introduce a 15nm process and then only 24 months after that the 11nm in Q4 2015. This is based on information in their official manufacturing roadmap.
Looking even further ahead the schedule also briefly discussing the possibilities of processors 80% smaller than even 11nm, estimating around the 7nm area. Intel are pretty good in keeping to their proposed deadlines and we would expect them not to slip up much with these estimations.
