Back in January, a trademark filing hinted that "Honest Hearts" would succeed "Dead Money" as Fallout: New Vegas' second DLC extension. A few screengrabs of a video briefly uploaded by Fallout maker Bethesda Softworks verifies that as the title and gives the briefest and tiniest of glimpses at its visuals.
A Bethesda forum user who subscribes to Bethesda's YouTube channel was sent an email notification about a new video uploaded - the trailer for Honest Hearts. The video, however, was set to private, then removed.
This is the link for the trailer, should Bethesda set it to public.
In January, The Vault (the Fallout wiki) noted that a graffiti file found in "Dead Money" referred to a "Burned Man" - Joshua Graham, and New Canaan. Graham was originally created as "The Hanged Man" and he and New Canaan were to appear in the version of Fallout 3 that Black Isle had been developing, canceled in 2003.
