After reading everything and some comments there. Look like Elop try to return to QT ecosystem which was planned before he entered Nokia. The QT ecosystem which should be initiated by N9 but sadly being halted. He try to squeeze QT in WP8 after realizing that it is difficult for WP to become the third ecosystem. That’s why he never mentioned about WP ecosystem anymore. Anyone notice that?
Nokia have seen the downfall of Symbian in 2009 and that is why the QT ecosystem was developed in first place. 2009-2011 was the transition time for Nokia from Symbian/S40 to MeGoo/Meltemi with QT based ecosystem. Starting with N9, Nokia should have start harvesting the seeds that they have planted in 2009 or earlier like PureView, fully touch UI, wonderful phone design and QT apps. Perfect combination that have been planned carefully to put back Nokia on top.
