Hehe, thanks buddy.
What I meant was that, quite literally, every server is a "global server", in the sense that anybody on the planet will be able to make a character on any server. Just like how the current servers are "global servers"; the only difference is the physical location of the new servers. There won't be any servers that only accept players from a specific region.
I hope that's a little clearer..?
Balmung and Massassamoonyunay will remain JP servers (in terms of location), just as they are now. The new NA and EU servers will have new, different names.
I do remember reading an interview in which Yoshida-san said the current servers (Ridill, Massassamoonyunay, Excalibur, etc) aren't going anywhere, physically, but I can't find it at the moment, so, until I can, we'll just have to settle for logic and inferring things from their (sometimes not-so-) carefully chosen words.
Additionally, the sensible thing to do would be just keep the current servers as is, in Japan, so that if that's what current players like, they're not forced into a change they don't want. Keeping as close to the status quo as possible, as it were.
For example, if I want to continue playing on my current JP server, I might be really pissed if it was "moved" to, say, Europe, without my consent.
Certain changes need to be made for the sake of the game's (hopeful) success, regardless of current players' desires, but they're not wholly inconsiderate or dismissive of said desires either. Not fucking about with the servers (e.g., moving Balmung and saying "GUIZ, YUR NAO A NA SURVER!! HAHA ENJOI!!") is one of the easiest ways of doing or showing that consideration.
My 2 gil, at least *shrug*
