Patches are region locked.. trust me. If you DL maps from the EU PS store and use them with a BLUS/BCUS MW2 game disk (rather than a BLES/BCES disk), they will not work.
DLC is a major problem for people who have game disks that do not match the region of their PS store. And the DLC is located inside the patch, which indicates that whether or not there is maps, the patch is region locked.
