You guys do know that, A) the "Nokia team" works at Microsoft now, and B) Microsoft also owns the tech and rights to all aspects of Lumia phones, both screen tech and camera tech.
This is actually wrong.
A) The Nokia imaging team works for Microsoft. But not the imaging R&D team. They're separate things. The imaging team at Microsoft works with the implementation of Nokia technologies into platforms. As the imaging team was dedicated exclusively to implementing that tech on WP after Eflop killed Symbian and the 808, it was expected that those guys moved to Microsoft (mind you, some didn't. Partinen, for example, left to go work for Apple's imaging team).
However, the imaging R&D is still done at Nokia. Which leads me to point 2;
B) Microsoft owns NOTHING of what you described. Nokia retained ALL the patents they had, including ALL the phone patents. They license the patents to Microsoft for Microsoft to use on their future phones, but the patents ("tech and rights" as you called it) remain all in the hands of Nokia.
And yes, Nokia is obviously developing imaging solutions. Because they kept all the patents, it's in their best interests to keep improving on them and creating new things. The more they create, the more patents they have to use and license.
And yes, it's possible that Nokia will be bringing their camera tech and all the new tech they're developing to other platforms, namely Android, since Nokia has moved to Android since the deal with Microsoft closed.
And it's possible that such tech arrives in the form of consumer products. If it will be a Camera-phone (like the Panasoniz Lumix one) or just a camera, or an app, or a phone, that remains to be seen. Let's not forget that until 31st December, Nokia can't put their name or license their name to be used on mobile phones. But they can put it on cameras, wearables, tablets etc.
Nokia WILL be at MWC next month. Maybe they'll shed some more light into what they've been cooking. Or maybe they won't. We'll see
