I've been using PyPy as my main development platform for quite some time now. So for me if I were to move to Python3, it would have to be Python 3.2 since that's all PyPy3 supports. I've also been told that PyPy3 is not production-ready. While PyPy4 is, so it's a no brainer for me to develop for PyPy4 then fallback to CPython2.7 if I run into problems. Fingers crossed, but so far my home business is running off pure PyPy4. No C-extensions, no interpreters. :)
