I would like to use Psyco with Python 2.7. I read that a branch was started. The news about this branch is from july 2010 but it seams as no changes have been done to this branch since february 2010.
Python 2.7 seams to be the last version in the 2.x series and will probably maintained longer than the usual 2 years. So making this "final" version of psyco seams to be worth it.
