Servers that are LOCATED in Europe/United States are not going to happen, Square Soft just doesn't have the resources to do so. The language barrier/time zones are also problems that would be needed to dealt with, so are maintainance and keeping the server up to date.
Would FFXIV magically have more than lets say, a million subscribers, THEN maybe they would start to enhance/backup their teams in europe and America. But before we don't get rid of the horrible image we're having now, the server will stay in japan.
