Pretty sure you can expect much higher capacities at launch, though, given the higher populations that they know they'll need to be dealing with. Plus you need to think beyond the first few weeks; there are always going to be parts of the game that aren't cross-server, and all of those parts are going to be a lot worse the fewer players your server has.
