I think you presume too much, Nokia still use Qt for their desktop Ovi Suite, which I doubt will change. They have also got a fair few more Symbian devices coming out, and Qt is their platform. We'll know a lot more in a year or two what they intend to do, but for the short term, 2-3 years, I'm sure they will continue to invest in the platform. Probably as much if not more than now.
