To be fair, the Python 3 transition timer shouldn't have had its tick starting until more recent versions of Py3. This won't be true for all Python communities (eg. Mathematics / Research), but until the more sane implementation of bytes/strings/unicode, the transition for most web frameworks or protocols was a mess.
However, from the later list, there are some really damning packages. For one, we're going to have transition off Twistd, which is much more than just an event loop. Py3 might not have enough advantage(s) to compel us to make that transition.
Honestly, I didn't check the dozen-plus packages pending update for us and then someone else cutting their teeth on it for a while, but Twisted was clearly marked as not being updated for Py3. But yes, clearly we're waiting; apparently Guido also wants to take a stab at the async batteries, which could help or hurt, if the Twisted contributors think they will be affected.
To the point of the comment you first responded to, there is lot of issues not being "solved" with respect to network libs, their upgrading to Py3, and Py3 looking to step into that arena. In other words, there is no horizon for networking libs updating, and they may feel even less motivated if the Py3 crowd is saying, "don't worry about it, because we are going to standardize our way." Does the Py3 transition-clock only start then?
I'm not really sure what your issue is. You use twisted. Twisted is currently being updated to support python3. Gevent has a branch which passes tests for python 3.3: https://travis-ci.org/fantix/gevent/builds/3588293 Is there some major library you are using that has no plans for python 3?
I'm not actually seeing an issue with python 2 -> 3 transition which is what my original comment was asking about. I see a lot of negativity surrounding python 3 and talks of fracture, but no actual evidence of it.
