Bethesda has said that there is a patch incoming for all three versions of Fallout: New Vegas, aimed at making the game a bit more stabile and optimized. The announcement came through the publisher's forums, where producer Jason Bergman writes that the developers at Obsidian have worked together with Microsoft and Sony to find the bugs that made the game freeze up and crash.
Bergman also confirms that there is a new DLC pack coming, and that we will hear more about it soon, but that the patch will be out before that is released.
