Maybe a new thread, but my 0.02 dollars, wait until 2011.
Passing both the SE I and SE II in the same weekend or same year is tough. Has been done, but tough. There will be added pressure becuase if you only pass one or the other, as I understand it, you will still have to take both sessions of the new one in 2011.
I think most study materials should still be relevant because the codes and standards will essentially be the same even though the format will change. I'm sure new practice problem books/exams will come out taylored to the new format.
Not sure what do you mean by limited exam taking possibilities? I believe the new exam will still be offered through NCEES in all locations, even if your state doesn't have an SE license. However, if you mean you're starting a family in 2011, TAKE THE EXAM NOW AND PASS!!!!
