I feel like I'm repeating the PEP, but here it is again anyway. There will be messages in the docs and pending deprecation warnings (which don't show up by default but can be requested) starting in Python 2.7 and 3.2. Regular deprecation warnings wouldn't show up until Python 3.4, 3 years away. This compromise was intended exactly to address the issue you brought up about people getting over the Python 3 transition.

For 2.x, I'd go even further and only have the PendingDeprecation warnings show up under the "-3" command line flag.

Cheers, Nick.
