Apparently, the Closed Beta will begin in about two weeks. The information was posted on MMOSite.
There has been no official statement from the Suba GMs yet, so we do not know how valid this is. Take it with a grain of salt.
This info is for all of you, who don't check the suba forums regularly.
EDIT: An officialt statement from the GM has been posted on Suba Games forums: HERE!
