Re: BF4 Premium Region

On Playstation3 the console can physically play anything from the world but the game and DLC MUST be from the same region or they will not see that the other one exists so your US BF4 will not see your EU China Rising. If you have a US BF4 you must use a US Premium subscription.

Also, technically only the purchasing account (in this case US) will truly be premium.  You EU account can use all of the maps and even the premium items and I think (it's been a while since I tested this with EU and US BF3 Premium and base game) complete premium assignments but your EU account will not show up as Premium in Battlelog.
