A sad story, really. Riverbank (effectively Phil Tompson), the copyright holder of PyQt could not reach an agreement with Nokia (previously Qt) so Nokia made it's own bindings. The stumbling point was probably the LGPL license, as Riverbank mainly lives from PyQt commercial licenses (like Qt did when they were solo). It's not really a surprise, after the Nokia buyout and Qt LGPL license a change was only a question of time. I believed they can make a deal (like buying out Riverbank or supplanting the lost income) and make PyQt an official binding, but in the end they went another way and we got PySide. The Python Qt bindings are dead. Long live the Python Qt bindings !
