Lonesome Road was originally to be released in May, but was pushed to July - and obviously, the DLC was passed over in that month as well. Bergman has reported that the DLC won’t be released in August either, but is promising ”other interesting FNV-related items in the near future.”
According to the forum post, ”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. 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.
We don’t have an exact date yet, but we’re working to get it out as quickly as possible. We’ll be announcing the final date, along with a couple of other interesting FNV-related items in the near future."
Lonesome Road would be the fourth expansion DLC released for Fallout: New Vegas, and will be released for PC, Xbox 360 and PlayStation 3.
