Jon ,what about moving to Python 3 ?
It look maybe a little late now cos it mean that every plugins written for ST2 Python 2.6 will need an adaptation for Python 3.
2to3 converter make the transition easier but not painless.
On the other hand Python 2.x work great so why change it right now, it could wait Sublime Text 3.
However, upgrading to Python 2.7 mean that you could write (theoretically) plugin compatible with both 2.7 and 3.2 using 2to3 converter, which could be nice.
