One thing they may be planning to do with the changes to 2.0 is make one giant server like Star Trek Online has. in STO, you are known as character@playerhandle, and if you'll notice in the concept screenshot posted in the 2.0 stuff, the players all have @something after their names. The way it works in STO is a zone can hold x amount of players, and once that zone is filled, another copy of the zone is created. This allows for zones not becoming too overpopulated, while also allowing the entire playerbase of the game to have the chance to interact with everyone else. I personally love that kind of server structure and hope that is what SE is planning for this game.
