I'm pretty sure that there will be more servers b/c we probably won't run on the japanese servers, but I don't know anything about the names (will probably be the same as the japanese servers). I have also heard the rumor that they stopped that, but I don't know if it's true or not. As far as I know, there is no other way of getting to a different server other than a world pass. Sorry. I have heard that World passes cost different amounts in different cities, but I don't have the prices.
