As a military member I am stationed overseas in Germany. My Xbox is still American as well as my Xbox live account.
The DLC for Black Ops was not available to me because of restrictions set up between xbox live/Treyarch/Germany.
Will they have the same issues with Black Ops 2?
Especially important considering that part of the Premium Elite is the included DLC. Or am I wasting more money for Elite to not even get the DLC drops?
I think there is no region lock unlike PSN. But I'm not sure about this one. What I can suggest is that you ask for assistance of Xbox so that this concern will be addressed.
