Should this be marked as Angular 2.0 BETA? The docs say that it is not done yet.

Also, the docs say that they do not know when they will be done. While I can understand that we may not know problem that arise, it is a pet peeve of mine that I never have a an idea when Drupal 8 will be released. I know that open source contributions are hard to track, we have to estimate (guess) when our projects will be done in our work, so why can we not do it for the projects we love?
