Video of HTC with keyboard leaked

There is a mysterious YouTube video of an HTC device with a slidout keyboard running Android. The poster of the video, TheIncarcerator, claims "A tipster sent this video to me. He said that the person that sent the video works for a company that makes a part for the phone."

Is this why we haven't seen any on-screen keyboards in the emulator? Even with a slide out keyboard we'll still need an on-screen keyboard for when we don't want to slide the keyboard out or want to keep the device in landscape mode.

Video after the break.
