That's a great question, its exactly what happened to a buddy of mine. He got the COD:MW3 Elite Membership card added in the code but nothing else happened with his Elite Status. The answers above are correct, the MS Points added will be enough to buy Elite
from the Marketplace. I wish the COD:MW3 Elite Membership card at the stores was more simular to the one given out in the 'Hardened' Edition, it was supper simple.
