I've been watching this pretty closely the last couple of weeks, trying to see which servers are getting full and which ones still have room. I've been hoping we get overlooked, so we have room for all of our fellow family members to get on. It's still looking good.
As of a week ago, Sanctum of Rall had 24 guilds claiming it as their home server and just our alliance. Today we have 39 guilds and 3 alliances. It would be interesting to know who the other alliances are on our server. This has to be expected getting closer to launch date that servers are getting filled up.
The other servers, aside from Anvil Rock, Borlis Pass, and a couple of other servers that people are avoiding are filling up much faster than ours.
Check it out. This is a pretty neat website to track the server action for GW2.
