> I assume you still need moc for SLOTs though, which if true is a shame. It would be nice to remove the need for moc entirely (or as much as is possible).
moc will never go away as it does more than signals and slots nowadays. Basically it adds the stuff that Objective-C has and that C++ is missing: introspection, properties and probably more.
> The other feature of note for me is the OpenGL work. Can anyone confirm if it's possible to build Qt to run directly on the framebuffer with a modern DRI2/KVM setup with accelereted GL? Or is X or wayland a hard requirement?
This kind of thing is handled by the QPA in Qt 5. You may want to look at the available QPA plugins: http://qt.gitorious.org/qt/qtbase/trees/stable/src/plugin...
