According to Khatie in this forum post, there is at least ONE way to be considered for early beta entry:

Until there is a beta capture process ready and up on our official website, we ask that anyone wishing to be considered for Early Beta Testing register on these forums. It's as simple as that! We'll be sending out invitations using the emails stored in our forum database as soon as closed beta testing begins over the upcoming months.

We can't wait to see you in the game!
