Sure, this could just be a really nice KIRF, but we've got a hunch these pics of an upcoming Nokia XpressMusic 5900 are the real deal -- it's just too understated to be shanzhai. Compared to the 5800, the updated handsets are said to feature a slightly larger 3.5-inch display, a five megapixel camera, and more or less the same build of S60 5th edition, all in a slightly thinner case. That's all we know for now, but we're told we'll find out more soon -- keep it locked.
