The time frame for the switch from Qt4 to Qt5 is the next two years,
because in 2017 Qt upstream ends support.

The time frame for the switch from Python 2 to Python 3 in the next 4-5
years (two Debian release cycles). The next stable release (stretch)
will still have Python 2, the removal is planned for the release after
that (buster).

Kind Regards,
