Does the Axon 7 support on-screen buttons?

[littlenoodles]

I've seen photos of the Axon 7 with on-screen buttons - and without the markings for the capacitive buttons on the bezel. Are there different models that treat the navigation buttons differently, or is this just some pre-release image that's polluting the ad-space?

And if on-screen buttons are supported as an option, can the capacitive button markings be removed (i.e., are they just some kind of decal)?
