I don't see the problem here.
1. Adobe is continuing the development of AIR and AIR 3 is coming to QNX.
2. RIM's Torch browser is one of the most standards compliant browsers out there, if not the leader. Even WebGL is coming to the platform.
3. RIM is also going to offer a native UI toolkit called Cascades and the demos look promising. You can also use Qt for native development.
edit:
4. ANd of course, there is also the Android app player supporting Android's UI framework.
