Nokia's big launch event tomorrow is expected to feature the brand new Lumia 920 Windows Phone 8 handset, which should come with PureView branding, just like the 808 PureView. Unlike its Symbian brandmate, however, the Lumia 920 is not anticipated to feature an enormous 41-megapixel sensor, raising some questions about what the PureView brand on the new phone will actually mean. In a series of tweets this week, Damian Dinning, Nokia's man in charge of cameras, has explained that PureView is about the overall camera performance, including optics, software, and image processing, and not the simple megapixel count.

You might say he's preempting the disappointment many people will experience when they see the PureView name attached to a sensor with a lower pixel count, but then, if his words are indeed correct and the Lumia 920 delivers image quality that's anywhere even close to the 808 PureView, does the pixel count really matter?
