In December, I wrote a post on the progress of the Wheezy release. Back then, we had 348 RC bugs in testing and today there are about 249 left. A bit of simple math put us at 99 RC bugs fixed since last and an average of about 2.4 RC bugs fixed per day (up from 1.8). Assuming a constant rate, we would be able to release in about 100 days or 3 months (plus 1 week or two) from now. If you want the release earlier than that, fix RC bugs even faster! 
Though, the data we are looking might be inaccurate. We filed a bug against UDD, which claims that #639407 affects Wheezy while it is in fact fixed as far as the BTS is concerned. If UDD is only wrong in this direction, we can hope for a positive surprise when the UDD bug is fixed. On the other hand, we may also be unpleasently surprised if not.
While talking about the UDD, I would like to mention a new feature its bug search script. It is now possible to filter based on whether or not a package is unblocked. If you take this into account (and assume that all unblocked packages will migrate in a timely manner), our RC bug count drops to about 219. It also gives us a much better view of how many packages that could actually use an unblock. which is now down to about 61.
In case you have been wondering what is up with the “removal of RC buggy leaf packages”. We have still been looking at those, but for the last couple of times there have been at most one candidate for a given run (obviously not the same package each time). It felt a bit excessive to send an email to debian-devel for just one RC bug.
