Fallout: New Vegas' Honest Hearts DLC Revealed?

A few months ago, talk hit the internet that Bethesda was readying New Vegas DLC, one of which was called Honest Hearts. Video evidence for this DLC has apparently been leaked.

A trailer for Honest Hearts has been taken down, but not before Duck and Cover grabbed this still. It looks and smells like New Vegas (and the fact that the trailer has been taken down only adds to the intrigue), but we'll have to wait and see if this is indeed true. Bethesda has an event this week, so hopefully we'll know for sure in a few days.
