Just have a look at V-Play, I can't wait until they release!
IMO, if QML some how like FXML in JavaFX (you can handle almost all GUI elements and its properties with FXML just like using java code, very easy to communicate between FXML and Java Controller class), I will love to use it.
At the moment, I do not exclude it, if it provides the components that I need, I will use it.
