"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," senior producer Jason Bergman explained in a Bethesda.com forum post. "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," he added without specifying a new launch window for the third DLC pack.
As a peace offering, Bethesda showed off the first image of Lonesome Road, seen above. If that's what taking the high road gets you, how bad must the other one be?
