Yes, soon is the safest answer ;)
But if I dare make an guess, 2 weeks max.
In any case, it'll happen in 2009.
There are tons of news in this release, we're revealing a lot this week.
But you can read what's been announced so far here: http://nekkidninjas.com/index.php?s=countdown&sentence=AND&submit=Search.
Make sure to read the comments, as we answer some questions about NB features and such.
CB, JomSocial (and maybe Anahita if we get the time) integration will be there.
Include HTML, Embed videos, those features might not be there in the 1.0 public beta.
But it could make it into 1.0 stable if there's an user demand for it :)
