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.
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).
