OSX Mavericks uses Latest Ruby and Python

As far as I'm concerned the 'latest' Python is 3.3.2

Python 2.7 branch is up to 2.7.5, so not exactly the latest (at least, not in the same sense as Ruby, where 2.0.0-p195 is the absolute latest stable release build of Ruby 2.0).

Great to hear. Which version of Python?

Python 2.7.3 (default, May 19 2013, 04:22:38)

Given your title, I was expecting the latest from 3k, but including 2.7 by default is probably better. People could get pretty upset if an OS update broke all their Python apps.
