For me it's been libraries which we rely upon which don't support 3.

True, I didn't consider the cost of updating packages (and any associated API changes). But in my experience there are very few packages that simply don't support Python 3, and the ones that don't are just dead.
http://py3readiness.org looks pretty good, most of the blockers for me (like twisted and a few others) are gone by now.
