From Trekmovie.com, shortly after the release of the 2009 movie:
GaryS: Was the timeline that Nero visited the original past up to the point that George Kirk is killed? Or was it always an alternate timeline because Nero was destined to travel there?
BobOrci: We think of it is as identical to the original until Nero arrives.

Somebody should ask that question over there, and see if they get an answer. Whether writing Star Trek Into Darkness has forced them to backtrack, in order to make the story they want to tell work.
