January's Halo 4 update 2013

Ok so i heard that in January 2013 everyone will be getting an update for specializations? I am one of the unlucky who played halo 4 after the 20th and got the regular edition, so i heard that everyone will begetting all the specializations in the update. Can anyone tell me when this update will come?

Smart move coming to the forums with that question, its not like the devs are keen to just telling the general public about, well everything!
