Note that this topic has been discussed in full and overly full length several times on this list. You may want to read up on it in the archives. I'm not sure if you're just trolling (posting suggestive questions with well-known answers is a well established troll metier) or if you really want an answer to your questions, but here's a short answer anyway. The intention of Py3 was to deliberately break backwards compatibility in order to clean up the language. The situation is not as bad as you seem to think, a huge amount of packages have been ported to Python 3 already and/or work happily with both language dialects. It's not an either-or kind of thing, you can have both with a little effort. And, no, there won't be a Py4 in 5 years. The established release time frame is way longer.
