A slip of an internal video has shown that HTC's got a 16MP cameraphone in its midst, but could it be too good to be true? That's double the megapixels that they've currently got on sale, so if this video is the real deal—which we're not too sure about—then that could be a pretty amazing handset, if you're of the megapixel-counting ilk.

The phone, as Pocketnow points out, seems to resemble the Desire S phone which was announced at MWC, only with a Windows Phone 7 button. Is it a placeholder, or just regurgitated hardware? With the just-announced Sensation being HTC's new flagship, it could be some time until we see something of this magnitude come along to disrupt the Sensation's footing in their offering—though it's been quite some time since HTC launched its WP7 handsets.

Either way, it seems pretty early for HTC to be working on adverts for this unannounced and no doubt someways-off handset, so it's likely to be a video for internal use only, at the very most. [Pocketnow]
