This is apparently the 4.5-inch Nokia Lumia 920 Windows Phone 8 slated for release on September 5. No solid specs have been revealed but some are saying that it might get a PureView camera. While we don't expect a 41-megapixel sensor on the next Windows Phone, it should be a pretty impressive shooter. Seeing as Samsung has pulled the trigger on its ATIV S Windows Phone, were certain to finally see some competition in the high end of Windows Phone 8 devices.
