Bethesda had planned on releasing a trilogy of DLC packs by the end of this month for Fallout: New Vegas. The first two went as planned in May and July, but the "Lonesome Road" DLC has been delayed.
Senior Producer Jason Bergman took to the Bethesda forums to detail the delay and give an explanation.
"We just wanted to drop in here and let you know that due to circumstances beyond our control, ‘Lonesome Road’ won’t be out this month," he explained. "This isn’t due to any major issue with the code or content, but there are lots of factors involved in releasing these things, and one of those is causing us to slip past our intended release date."
Bergman went on to state that the DLC team is "working to get it out as quickly as possible," so a new release date should be announced very soon.
