The above should be taken as reporting, accurate or not, rather than 
advocacy.

To the best of my knowledge, 2to3 is not being adjusted on a per-release 
basis. I am for doing this, but as I remember, there was some opposition 
when the question was discussed on py-dev. If I am wrong, I would be 
glad to be corrected.

That would be my attitude too. I would hope that most of the major 
library are available for 3.2 before 3.3 is out. There there would only 
be the normal minor adjustments for code that happens to hit the new 
deprecations.
