I know for a fact that the testers don't know when a new version is coming out. They may know it is coming soon, because of posts by Badspot saying that everything that needs to be done is, and that he's just checking everything over one last time, but they don't know if it really is coming out when he says it might, because he will delay it for any bug fixes. He doesn't tell us a date because he doesn't want to be forced to release it with some bugs, and he also doesn't have any reason to wait when everything is working fine.
