As for the server polls, I would assume they are either going to open the forums back up prior to pre-select, or if not have the poll on the Aion homepage. But they'll certainly be holding it before pre-select or else it would defeat the purpose.
And about the launch time, I think it's 9am on Sunday, 20th that the servers go online. In the past beta's they've usually had a 9am start.
For sure we're going to coordinate servers Anu. That's what I wanted one of the purposes of these forums to be
It's too bad they're making it hard for EU and NA players to play together though. However I did hear at one point that they may look into opening them all up across the board sometime after launch once they get an idea of regular server population, so I'm going to keep my fingers crossed for that.
Edit: I did some more looking around and found that Ayase, one of the Community managers mentioned on his twitter page that the poll should be taking place sometime this afternoon. (No I don't follow twitter, I found a link to it on the ARP site) But it's a pretty vague post.
