Kind of off topic, but what the heck, I'm bored today. :) Typically, it's dependencies and the cost of the effort to address them. Python 3.x literally made language changes that have the potential to break existing 2.7.x scripts, and I'd imagine the 2.7.x line still has a huge amount of production dependency (I know it does for us). You can spend the time retooling your product, and introduce the one-way upgrade in a new release, but that trickles down to your customers, forcing them to spend time updating any collection of Python tools they themselves may have created. Personally, I've not seen anything in Python 3.x that is sexy enough to make me want to put forth the effort. I have yet to run into something I cannot accomplish using 2.7.x that 3.x makes possible (which is likely another reason that the transition is so slow).
