I don't think counting Python 3 support is really important for Web frameworks. All of the major server distros are still on Python 2.x anyway (last I checked, Arch is the only one where "pacman -S python" will get you Python 3 instead of 2), and the question of WSGI is still up in the air if you want to handle encoding properly instead of just fudge it.
