A video of what appears to be HTC 8X marketing material has been leaked on YouTube, and it reveals an interesting feature of the Windows Phone - LTE support. Earlier last month we took a look at the HTC 8X sporting the Verizon 4G logo, which further confirmed -- alongside the leaked roadmap -- that the US carrier would indeed be taking the handset under its wing, and that it would be compatible with greater network speeds.

The HTC 8X was recently spotted downtown San Francisco for what we can only assume to be carrier testing and optimisation, but it's hard to tell. For the HTC 8X to be compatible with LTE connectivity makes sense due to both the manufacturer and Microsoft billing this as a hero Windows Phone.

Back to the video, we can see the "4G" connection status being displayed throughout, and while this could well be just a holding band in marketing efforts, we'd like to believe this represents what the Windows Phone will actually be capable of with regards to speed and compatibility. Of course, to be featured on the fast US carriers, one will have to boast such compatibility.

We're expecting to be able to grab the hero Windows Phone on AT&T, T-Mobile and Verizon in the US these coming weeks. While there's nothing to say this video isn't official, we'd like to sway towards everything being in order. Of course, should this be official marketing material, we strongly doubt HTC would make the mistake in misleading customers on whether or not LTE is supported.

For reference sake, the 8X sports a 4.3” Super LCD2 display with Gorilla Glass2 at 720P resolution. Joined by a 1.5GHz dual-core Qualcomm S4 CPU, 1GB of RAM and 16GB of non-expandable storage. The 8X boasts an extra internal amplifier and Beats Audio to improve sound quality through the use of dark magic.

To close up, who's excited to get their beastly hands on their own HTC 8X?
