Right now it still looks like 2014, with delivery starting in late '14 to early '15. According to the budget, the Marines are slated to get 16 35B's and the Navy 4 35C's in 2010. For a look at the 2010 Aviation budget breakdown:
The Navy and Marines I could see more as a starting basis for the F-35. So 2010 eh? I wonder if any prototypes have started carrier trials. Concentrating on the carrier aircraft first is always best, since it is easier to "de-carrier" an aircraft design than adapt a land-based aircraft design for carrier use. In the meanwhile they should continue to concentrate F-22 production on replacement for the F-15C.
