The linked article says "Nokia showed me poster-sized samples captured with the 808 PureView (printed entirely unprocessed) that basically had zero noise in them."
It is probably a very good camera, but together with Symbian I fail to see the point of it, the market for Symbian high-end camera phones must be minimal at best.
Unless possibly if it is a 'prototype' that they decided to sell to try and convince MS that they need to be able to do similar stuff but with Windows Phone.
I still remember the hype around the (5MP?) camera on the N95 back then. Even the Nokia published samples were horrible, but the press made it sound like that was the best camera phone ever...
Processing the pictures took forever, but the results were quite nice. Look at this one I shot for example: http://www.flickr.com/photos/bergie/5293597184/in/set-721576...
