A sharp eyed subscriber to Bethesda's YouTube channel spotted the company uploading a new video, presumably of the next piece of DLC for Fallout: New Vegas. The video is still private, but we know it's titled Honest Hearts, which kind of sounds more like a twee indie record than a game where bad guys' heads explode.
Right now it's just a few images, and there are no solid details about the add-on, but feel free to start speculating. More likely than not an actual video will show up with an announcement before too long. DLC seems to be trickling out a bit slower for New Vegas than Fallout 3, possibly because of the smaller scale of the sequel, or maybe they're just trying to avoid the kinds of bugs that the main game suffered from when it came out last fall. Or perhaps they just had to wait until the limited-time Xbox 360 exclusivity for the Dead Money DLC expired, and wanted to give PC and PS3 gamers time to play through the pack before releasing another.
