Well, it was their strategy all along with Qt, but it's been slow ride. Everything is Qt on new Symbian, MeeGo and upcoming Meltemi. Qt is natively on the new BBX and will probably be on Android. Qt is also their main strategy besides WP, so we will see how things pan out.
If I'm correct, the Qt Lighthouse is integrated in Qt 4.8 (now RC1), which means easy porting for any platform, including Android. Remains to be seen if Nokia and Google come in terms with this officially though. Of course, you can already distribute Qt apps on Android, using third party ports like Necessitas: http://labs.qt.nokia.com/2011/02/28/necessitas/ .
