I too would really like to know this soon, I currently don't really know what to do as I have lots of friends on one of the early access servers that has only recently opened up to new character creation, but I've now got a lvl 30+ char on a different server because that was the only one available when I started playing. So I could now easily start a new char to join my friends but if character transfers are only a week away I'd probably be better off waiting.

Just some information on a timescale would be nice.
