The current realistic estimation would be « when it's done ». At first
we thought we were to branch in February, so...

Recently, a relatively important number of inconsistencies in Coq have
been discovered, mainly thanks to Maxime Dénès. The one on proof market
was a DeBruijn overflow in the kernel, dating back to the beginning of
ages, if I remember well. (But it was rather difficult to exploit, though.)
Yet, after the merge of the polyproj branch, the trunk needs quite a bit
of polishing. It is known to be inconsistent for stupid reasons, but
hopefully that should be solved soon.
