Unlocking Specialization

So if you dont have LE am I to assume that the 6 specializations that you should have if you play before Nov. 20 are to come out on Nov. 20?

Im trying to be a rogue but only have wetworks and operator available. I dont have the storage space for the LE map pack so do I just wait to unlock rogue on the 20th or is there a faster way?

Anyone have any idea?

I believe the add on xbox live said, play the game online before the 20th of Nov. and sometime between the 20th and 30th you will receive a code in an email associated with your xbox live account to unlock the specializations.
At least this is how I understood it.

In the small print they said the codes will be sent out November 30th.
