matplotlib is the defacto standard for plotting data in Python and could definitely be considered a hurdle. I haven't followed to closely but it looks like support for 3.x is coming along nicely[1]. GUI toolkits like wxPython and PyQT/PySide supporting Python3 will also be important. I'm not sure how outdated this is, but there's a list of most wanted Py3k packages available here: http://www.python.org/3kpoll http://www.python.org/3kpoll 1. https://github.com/matplotlib/matplotlib-py3 https://github.com/matplotlib/matplotlib-py3
