I have some interesting news guys. Trion isn't considering open beta the actual launch date and will wipe after open beta. There is literally no reason to play until launch, which doesn't have a set date.
In any case, if you want to play the game you are better off playing the RU version because the NA isn't actually being 'launched' for quite some time.
Trion's naming scheme;
Closed beta is called Alpha
Stress tests are called Closed Beta 'Events' & Open Beta
