Is there a kind of count down?

Well, on top of the main page one can see a lot of source activities. But that does not imply to get an idea on how far a next release would be. Of course it would be very difficult to schedule a precise date. But how about another kind of info, based on the percentual rate of still to be solved tasks or problems. Actually it is nearly impossible to get any impression of the nearness of the coming goal.
