How will we get Specializations?

So, for the people that got the standard edition of the game, how are we going to get the specializations if we played before the 20th? Are they just going to unlock, or will we get a code or what?

I got the standard edition but was given a code that unlocked all the specializations because I pre ordered it.
But yes they unlock for everybody after a while

You’ll get a code sometime before the 30th that unlocks all the specializations (If you played before the 20th, that is)
