UPDATE: "Project Louisiana" is Pillars of Eternity 2, not Fallout: New Orleans. Obsidian has confirmed that it isn't currently developing a Fallout game, despite their desires to do so.
Original story is as follows.
Obsidian Entertainment is teasing "Project Louisiana," a new upcoming game that could very well be a new Fallout game based in New Orleans.
We know next to nothing about Project Louisiana, but Obsidian did drop some clues in two teaser images that you can find below. The first image hints an agrarian society tied to a religion, and could very well be the mainstay of a post-apocalyptic village or town out in the country. The image also shows what appears to be a flag with a coat of arms made up of an ax and a wheat stalk. While I'm hoping against hope that this is Obsidian's triumphant return to the Fallout universe, the images below, which were found on the http://www.obsidian.net/la/ webpage, don't really seem very Fallout-y:
"You know better than anyone that nothing is more dangerous than a god's secrets. Perhaps the Leaden Key was right to keep this one buried," reads the quote on the blue image, which shows what could be a flag of a ornate key on a field of blue.
