From what I can gather there are substaintial works going into 2.2, and due to time being given (not paid for) by the dev's I don't think that anyone can really give an accurate time estimate. I think (as in don't quote me on it) I read a post from Herko some months back that they hoped to be approaching a beta/rc by the end of this year. Again, things may have changed, and I may have imagined reading it.
