There may be some at first:

We are expecting major congestion during the period starting with the Early Access on Aug. 24, 2013 at 2:00 a.m. (PDT) leading up to the official game launch on Aug. 27, 2013 (PDT).
If a large volume of players attempt to log-in to the game simultaneously, certain players may receive the following message: “This World is currently full. Players in queue: ##.” If you receive this message, we ask that you please wait until your log-in is processed.
In addition, in order to avoid server congestion related issues from multiple characters concentrating in the starting areas, we may implement restrictions on log-in(s) and/or the creation of new characters for a period of time after the servers open to the public.
