Out here in Cali, we have Title 24 energy compliance in full force, as well as most jurisdictions that are at least up to '05 NEC AFCI requirements, and '08 is implimented in some pockets. Almost every municipality in Orange County has their own building department with their own adoption/update schedule, and of course each inspector has their own take on any particular code that may be slightly vague.
It's not unheard of here to have 3 jobs, 3 miles apart, under 3 different versions of the NEC. Confusing? You bet...
I would imagine, with the political and social climate regarding energy consumption, that we will see many changes and revisions in device and fixture requirements in the near and distant future.
Take a quick look at Californias Title 24 if you get a chance - it may be an indication of legislation headed your way - if it hasn't already gotten there.
Good Luck!
