Fallout: New Vegas DLC hinted at in trademarks?

What we heard: Dead Money, the first batch of downloadable content for Obsidian and Bethesda Softworks' postapocalyptic role-playing game Fallout: New Vegas, arrived in December to a cool reception. However, recent trademark filings indicate more DLC is on the way for the game.

Bethesda parent Zenimax has applied for a trademark for "Honest Hearts" for use in "computer game software for use with computers and video game consoles; downloadable computer game software offered via the internet and wireless devices." The Fallout connection comes courtesy of Fallout wiki The Vault, which points out that "Honest Hearts" was first hinted at in Dead Money via a texture folder dubbed "nvgraffitihonesthearts."

Two other recent Zenimax USPTO DLC filings, "Old World Blues" and "Lonesome Road," are listed by the Vault as the titles for two more expansions for Fallout: New Vegas. The Vault points out that the latter title is featured in in-game graffiti in the original title, although the former has no formal Fallout connection other than rumor.

The official story: As of press time Bethesda has not responded to GameSpot's request for comment.

Bogus or not bogus?: Given Bethesda's history of supporting Fallout titles post-release--Fallout 3 had five expansions--it stands to reason that Dead Money will not be the final add-on content for New Vegas. However, it is unclear whether or not Bethesda intends to build content surrounding each trademark, or if one or more are simply red herrings.
