A user on the Obsidian forums named UrbaNebula spotted a new Obsidian trademark yesterday, for something called The Outer Worlds. They've actually trademarked it for four different purposes - computer games, gaming-related online services, gaming-related literature and board/card games - which suggests that this is a large, AAA-caliber enterprise. In other words, we may have just learned the title for Tim Cain and Leonard Boyarksy's unannounced game, currently known only as Project Indiana. Take a look:

Congratulations on the scoop, UrbaNebula. It's worth noting that this trademark appears to be owned directly by Obsidian, and not by the "Dark Rock Industries Limited" shell company that owns the Pillars of Eternity trademark and intellectual property. Whether that means anything is yet to be seen.
