Despite the shift towards Windows Phone 7, Nokia will still ship a MeeGo device this year. It's going to be the successor to the Nokia N900 and will be called the N950. We don't have a photo of the device yet, but Nokia gave reassurances that they are committed to MeeGo, Symbian, Qt and S40 too.
At Nokia's Developer Day, Nokia's CTO Rich Green gave an extensive talk about the future of current Nokia platforms, included. He said that they're working hard on the N950 and have come up with some "very elegant" hardware and interesting UI.
That's all we have on the Nokia N950 - the Nokia N9 (which was rumored as the coming MeeGo device) might have been canceled and Nokia showed absolutely no new devices at the MWC.
Anyway, here's a video of the talk. It starts off with N950:
Green assured the attending developers that the Nokia N950 is well-stocked as a developer platform and says "we'll see how that goes". It sounds like the N950 is aimed more towards devs than the mass market user (not surprising since MeeGo was re-targeted towards long-term market exploration).
Nokia's strategy still relies on Qt development for both Symbian and MeeGo and pushing forward with Java on Series 40, so work on those platforms continues. S40 will be getting a new Ovi Browser that aims to bring mobile Internet connectivity to hundreds of millions of people.
