The big one is that Python 3 holds the future of Python development.
There are no more feature releases planned for the 2.x series, only
maintenance releases.  Eventually, Python 2.7 is going to start
looking pretty old.

You might look through the whatsnew documents at:

http://docs.python.org/3/whatsnew/index.html

to get an idea of what features have been added in Python 3.  Many of
these have been backported to Python 2.6 or 2.7, possibly requiring a
__future__ import, but most have not.  One change that comes to my
mind that might be of interest for NCLab is that in Python 3.3, the
decimal module has been rewritten in C for a major speed-up.
