Now the developer story is easy to explain: Qt is the Queen, Qt Quick is the King and Qt Mobility is the Wizard. That's it. All the rest is now tagged as legacy, which means that the teams working on these frameworks are now planning the way forward to contribute directly to Qt's speed and success. If you are an application developer interested in MeeGo / Symbian the path is clear. If you are interested in alternative paths that's fine, but up to you.
