This could be the HTC One Windows Phone (Update)
UPDATE: This video has also leaked fro Verizon.
HTC is expected to unveil its HTC One Windows Phone next week, but ahead of that this image has leaked clearly showing the handset in all its metallic glory.
The HTC One Windows Phone photo was sent to Neowin by an anonymous source. Normally that might ring alarm bells but this image is of such high quality it's clearly a professional shot that's leaked, likely from Verizon judging by the rear case.
The full spec sheet for the phone has also been leaked. It sounds like it will keep the Windows Phone 8.1 OS running smoothly and looking stunning.
There's a quad-core Snapdragon 801 processor running at 2.3GHz backed by 2GB of RAM. Onboard is 32GB of storage and there's a microSD slot for a further 128GB expansion.
The many Windows Tiles should look sharp on the 5-inch 441ppi screen that's coated with super strong Gorilla Glass 3. There's a 2,600mAh battery which should deliver plenty of life even when getting lots of use out of the UltraPixel camera on the rear or 5-megapixel selfie camera on the front. It also features U-Focus which uses dual camera lens smarts on the rear for greater picture depth and quality, says HTC.
Of course HTC BoomSound is included on those two front-facing speakers. It will also work with HTC's popular Dot View case that allows the user to display data with the case front closed, without using too much battery. It will also, reportedly, add support for use of the Cortana voice controlled assistant while the case is closed.
Expect to hear the official lowdown on the HTC One Windows Phone next week, when it's rumoured to be unveiled.
