Things are looking pretty good over on the Python 3 branch, thanks to the great work done at CTPUG, Sage Days 29 and elsewhere, and it probably bears some discussion about where we'd like to go from here.
I'm thinking we should probably do another 1.0.x release with all of the bugfixes we currently have on that branch.
Then, the question is when to start treating the py3 branch as master. The only downside on Python 2.x (that I'm aware of) is the dropped support for Python < 2.6. There are still a number of reasons (mainly due to external library dependencies) that one may not to run matplotlib on Python 3.x, but that's a separate question, IMHO.
The status of the Py3 work is here:
I would love a Mac user to build and run regression tests on both Python 2.x and Python 3.x, and run some interactive examples, particularly the mac os backend, as I haven't been able to test that personally.
