In what appears to be an accidental listing (which has since been removed) the official Xbox website revealed a new title in its game database over the weekend, titled South Park: The Stick of Truth (via: NEOGaf).

Although it's possibly only a working title, the boxart is clearly attributed to THQ's upcoming South Park RPG, in development at Obsidian Entertainment, however, THQ has yet to confirm an official name for the game, referring to it only as "South Park: The Game" in previous press releases.

Interestingly, the listing also indicated that the game would support offline co-op for 1-2 players, a feature that THQ has yet to mention. However, given that the release date on the listing was the clearly erroneous 5/5/2012, we're taking all of these details with a grain of salt.
