More or less. It was first discussed at the language summit last year and
has come up here a couple of times. If needed we can make it official in
terms of lifetime of 2.7, etc. at the language summit this year.

I don't think ending the 2.x series at 2.7 makes it look bad compared to
3.2; it's simply the end of a development line like any other software
project. I suspect 2.7 will have a protracted bugfix window because so much
code runs on 2.x exclusively at the moment. And if core developers want to
continue to backport fixes past two years from release they can (or however
long we decide to officially support 2.7).
No one is saying people still can't work on the code, just that python-dev
as an entity is not going to focus its effort on the 2.x series anymore and
people should not rely upon us to continue to focus new development efforts
in that series. If there are core developers who want to continue to do
bugfix releases then that's fine and I am happy to flag patches as needing
backports and let other's do the work after the standard two year
maintenance cycle, but I know I do not want to be held accountable as a core
developer to keep the 2.x going indefinitely. Maintaining four branches is
enough of a reason in my book to not keep the 2.x series going.
If there really is an outcry on this we can re-visit the issue, but as of
right now we need to move forward at some point and 2.7 seems like that good
