New add-ons for Bethesda and Obsidian's Fallout: New Vegas are being rumored, due to recent trademark filings by ZeniMax Media, the parent company of Bethesda, the owner of the Fallout franchise.

Barely has Fallout: New Vegas received the Xbox 360-exclusive Dead Money downloadable content, and speculation has already begun heating up about the next pieces of new content for the role-playing game.

We already heard that one new adventure might be centered around another courier from the Mojave Wasteland, Ulysses, but now we have even more concrete details.

According to the Fallout Wikia website The Vault, three new trademarks were filed by ZeniMax, Honest Hearts, Lonesome Road and Old World Blues, with the first having a series of graffiti markings associated in the file.

Honest Hearts, according to the Vault, might be associated with the beginnings of Caesar's Legion, specifically with Joshua Graham, otherwise known as the Burned Man.

Joshua Graham was Caesar's right hand man, but was killed by the ruler of the Legion after the humiliating defeat at the Mohave Dam, being lit on fire and thrown into the Grand Canyon, earning him the Burned Man nickname.

The graffiti markings say that Graham may be alive, and that he is heading to New Canaan, a city controlled by Mormons north of New Vegas.

Both Honest Hearts and the Lonesome Road were hinted at during the playthrough of the first DLC for Fallout: New Vegas, Dead Money, while the Burned Man was talked about by lots of non-playable characters in the regular game.

Nothing else is known about the Lonesome Road or Old World Blues, however.

It's worth pointing out that both Joshua Graham and the location of New Canaan were both scheduled to appear in the canceled Fallout 3 project, codenamed Van Buren, from Black Isle studios, the creators of the franchise.

Seeing as how Fallout: New Vegas had a closed ending, with almost all of the narrative threads tied up, the future downloadable content may focus on other playable characters, possible The Burned Man or Ulysses, and expand their own adventures.

As of yet, this is still speculation, so take it with a grain of salt.
