"Speculation Surrounds Possible 'New Vegas 2' Content in Fallout 4 Update"
A recent Steam update for Fallout 4 contains a reference to "New Vegas 2," but it's unclear why. The appearance of a new branch titled 'newvegas2' on SteamDB has sparked speculation, but it could just be an internal test build of the new-gen update for Fallout 4. While hopes for a New Vegas 2 game are not entirely unfounded, Obsidian has repeatedly said it's too busy to commit to such a project.
