Halo 4 Limited Edition Codes

I pre-ordered the Limited Edition Halo 4, and I got the codes for the specializations, and the map packs. I haven’t received any maps though. I think it’s because no new maps have come out though. Also, Xbox live has sent me a message saying " Here is your token to unlock six specializations in Halo 4. We apologize for the delay in providing this and thank you for participating in our program. See you on the virtual battlefield!" Then, it shows a code. My specializations code already works though, so I think it’s either a mistake or this is to fix the maps. Please post your thoughts. I just want to make sure it’s not anything i’m missing. If i already have everything, i’m planning to give the code to my friend.

Yes give the code to your friend.

Yes, give it to him over a random stranger. Completely reasonable.
