Your wish is my command ! ;-)

Here's the doc:

http://docs.python.org/3/whatsnew/3.0.html

Issues I think might need attention (but this is without verification 
within the grass python code):

- Print Is A Function
- Views And Iterators Instead Of Lists
- PEP 0238: An expression like 1/2 returns a float. Use 1//2 to get the 
truncating behavior.
- Text Vs. Data Instead Of Unicode Vs. 8-bit
