A video discovered on YouTube appears to be promotional material for an upcoming HTC Windows Phone smartphone sporting a 16-megapixel camera.

The video, first spotted by Pocketnow.com, is mostly animated with a glimpse of a handset at the end showing a familiar HTC design. The voice-over clearly says, "with a 16-megapixel camera and two LED flashes, even a phone can give you professional shots," and if this video is legit it would make this the highest resolution smartphone camera sensor to date.

Further speculation surrounds what appears to be a front-facing camera on the handset render seen at the video's conclusion, suggesting a video-calling feature not yet available in Microsoft's platform. We know that Redmond is preparing a major firmware update in Q3, so perhaps this mystery handset and its outrageous specs could be the flagship model to show off the many new features of this update.
