I started writing this last night before the flurry of messages which arrived overnight. I thought originally, "Oh, Skip, you're being too harsh." But now I'm not so sure. I think you are approaching the issue of 2.7's EOL incorrectly. Of those discussing the end of Python 2.7, how many of you still use it in your day-to-day work? Have any of you yet to move to Python 3? It sounds like many people at PyCon are still 2.x users.

Where I work (a trading firm that uses Python as just one of many different pieces of technology, not a company where Python is the core technology upon which the firm is based) we are only just now migrating from 2.4 to 2.7. I can't imagine we'll have migrated to Python 3 in two years. It's not like we haven't seen this coming, but you can only justify moving so fast with technology that already works, especially if, like Python, you use it with lots of other packages (most/all of which themselves have to be ported to Python 3) and in-house software. I think the discussion should focus on who's left on 2.x and why, not, "yeah, releases every six months for the next couple years ought to do it."

This thread is about setting CPython release schedules, so that the discussion focuses on that is unavoidable. :)

I don't think the bug fix releases of CPython are critically important to the life of a Python version. Every 2.x version has survived much longer than Python-dev has done bugfixes on it. As has been noted on this thread, there will be commercial and apparently PyPy support for 2.7 long after cpython stops bug fixing it.
