Of course I can't tell you if Nokia will bring a rotated UI. No one here can tell you.
We're not Nokia.

If Jussi didn't tell you then there are few reason why.
It can't be said yet.
They don't know yet.
They won't do it and don't know yet how to tell it.

I am sure they talked about it, and made a decision about it.
We simply don't know it. And if you asked Jussi about it and Jussi didn't say anything, than you simply have to wait and keep asking.
File a bug or a brainstorm idea and Nokians will reply sooner or later.

But it should be pretty clear that for now, when the device will come to the shelves, there won't be what you're asking.

I am sure they won't add anything new now.
I would like to have portrait UI fully working, I am used to it in the few months I had an Android phone, but I don't mind and I don't see it as a limitation, but I do see how many people see it as such.

At least, that's the only think I can tell you, my own application will rotate.
