when will it be sent out exactly?
is this limited to US?
where can i read the official info about this all?
if i unlock specializations with my LE code now, will i still receive the code per mail (for giving it to friends or something like that)?
I dont think we will get a code, it will check our player data most likely and unlock them if we played the game before November 20. Basically a automated system like the banhammer or when 343i unlocked Recon to us all in Halo 3. But i could be wrong.
