Obsidian Entertainment Working on Alien RPG?

Gaming Target is reporting that Sega's official Aliens website listed Obsidian Entertainment in the copyright information at the bottom of the page earlier today. However, according to their newsbit, Obsidian's name was removed from the copyright text shortly after the news broke. Considering that today's announcement mentioned development of a role-playing game based on Twentieth Century Fox's popular franchise, it seems very convincing that Obsidian Entertainment is indeed involved.
