"There is high probability that Python 3 is such a failure it will kill Python" - Zed Shaw. As Curator of a Python Newsletter for 2+ years I can tell you at-least 20-30% of all articles I read of late have code written only for Python 3. Just recently I was at Pycon India and met lot of student who never wrote a single line in 2.x. Startup founders starting with new development choosing Python 3. Lot of people are sleeping on Python 3. A year more and hopefully everyone will be awake.
