2) They have only added 1 server to each group (NA/EU/JP) AT THIS TIME. They have other servers ready to go. BUT, they'd rather let these new ones fill up and once full release another then have a bunch of new servers half full. Makes sense to me.
I could see this being the case. Nothing has been said about being able to transfer existing characters to the new Worlds. Since playing on a new World requires starting over, they may not be expecting too many players willing to take advantage of the new World.
They would need about 6.25% of the player base (1 in every 16 players) from each existing NA World to be willing to start over to evenly distribute the existing player population across all Worlds. If they had added 3 new Worlds for the NA data center, you would need 16.7%, or 1 in every 6 players. If you don't get enough of players to start over on a new World, then you wind up with underutilized servers that aren't helping anyone.
Note: the math I did is pretty straightforward. The percentage of players you need to start over comes out to 1 - y/(y+z), where y is the number of Worlds before maintenance and z is the number of new Worlds added.
