I guess there will be support and a "spiritual" successor. I just don't see nokia wasting billions on the N9 and then abandoning all its tech. The UI and Qt is gonna survive, and so will its apps. I doubt it will remain high-end though. I think nokia will tell us more about the purpose of the N9 in the next 2 months or so. Just wait til then.
If that happens I'll be very pissed... N9 not out for even a month, nor had a chance to prove itself. Before they totally bury the chances of there ever being another high-end ph like it.
Anyone that dares to ignore Chuck Norris should be punished and kicked off this forum. My respect for you Mr. Norris.
