A snap of the long-rumoured device, alternately called the HTC Accord and HTC 8X, was acquired by PhoneArena, showcasing a handset boasting the logo of U.S. carrier Verizon Wireless.
The navy-blue styled handset looks a lot like the recently announced Nokia Lumia 920, which also features a square-edged candy bar form-factor.
Beats on board?
HTC's first venture into the new version of Microsoft's smartphone operating system is widely expected to include an 8-megapixel camera and a 1.2GHz dual-core Qualcomm Snapdragon CPU.
According to the report, there's no room for a microSD card for expandable storage, but previous leaks have suggested both 16GB and 32GB models will hit the market.
Also rumoured to be laying within the Accord/8X is a 4.3-inch touchscreen, built-in Beats Audio technology, NFC connectivity, 1080p HD video recording, and 1GB of RAM.
HTC is holding a media event in New York Wednesday, which kicks off at 4pm UK time (11am EDT), where it is expected to unleash a trio of Windows Phone 8 devices.
