He said that the Japanese have been using the pixel zoom technology of the PureView 808 in their commercial cameras for a year now, so the technology isn't anything new.

One thing we might get on board with Paul Genge about is the "retail solution" part - while Symbian Belle will do the job, the vast majority of potential Nokia customers for this 41MP cameraphone wish the PureView Pro technology were housed inside a Nokia Windows Phone device. There is no point in prejudging before the actual device gets in the hands of our reviewers, though, so we are patiently waiting.
