I believe that what ever is going to be released at some point in time, is a Beta. What the dev team is doing now is alpha testing there creation. And it will be finished when the team feels it is good enough for a wider audience.
I don't know why this can be so hard to understand for anybody :)
In the group where I'm playing we have been following this very close. We also hope for a release very soon so that life as a Tatical ArmA gamer becomes even more fun.
