As someone maintaining packages on pypi, I can tell you that demand for Python 3 support is growing and people are beginning to port packages for their own needs. I expect we'll see python 3 overtake python 2 in new projects within 3 years. I realize that's still pretty far off, but these things take time. You have to give the PSF credit for great support of the 2.x series.
