Just to clear this up, all versions of Qt5 have always been available for free
under an open source license, just an earlier version of the LGPL (version 2.1,
to be precise). The recent change was just that Digia is also adding LGPLv3 as
an option. The differences between the two versions are relatively minor details.

However, PySide does not at the moment support Qt5. I think it's mostly a matter
of committing resources to porting the wrappers to the Qt5 API and supporting
both Qt4 and Qt4 simultaneously. I'm not sure if there are any technical
showstoppers, but I don't think there are any. There are certainly no legal
showstoppers. It's just a matter of some volunteer finding the time to build and
support the Qt5 wrappers.
