I really wouldn't read too much into that, it looks like it's just a concept screen and most leaked Nokia concept stuff never makes it off the drawing board. (For example a few years ago there was a huge spate of leaks of a "Nokia Neo" device with no keypad or touchscreen, just a circular dial, but it was never actually released. And there must have been two or three leaked "N96"s which bore no resemblance to any released phones.)

On top of that, Q4 2010 is such a long way away that no one could possibly make a decision on such a project right now anyway.

Also, the people writing the article aren't exactly researching things properly - they refer to "Symbian S40 and S60"... S40 isn't Symbian and anyone serious about phone OSes should know that. It would be like writing an article about desktop OSes and talking about Microsoft Linux.

EDIT: Just to give a further example of being cautious about taking leaks too seriously, I once got a scoop by obtaining a genuine internal Nokia document which contained all their plans for the new N-Gage platform. A lot of the stuff in the document simply never happened, it was stuff that was planned and some of it even announced at some point but never actually carried through.

Closer to home, the Nokia 7700 was supposed to be their first touchscreen device and that too never actually went into production despite prototypes being sent to reviewers.

I'm not saying anything about this leak is wrong, I've got no idea whether it's correct or not. I'm just saying that all leaks have to be taken with a very very large pinch of salt as it's impossible to be certain which concepts and products actually make it into the shops.
