Apparently, Frictional Games has announced another project. Not only that, but they seemed to have bought this domain: http://www.nextfrictionalgame.com/
Clicking it will bring you to a picture of this http://www.nextfrictionalgame.com/image_1.jpg but with the Amnesia logo and the words, "Something is emerging..."
Clicking on it will bring you to this: http://www.nextfrictionalgame.com/inject_db.php
In this site, it says that a "machine for pigs" is coming this fall. Clicking the second half of the sentence will bring you to this: http://www.nextfrictionalgame.com/image_2.jpg
Frictional Games also licenced another website called http://www.thedarkswarm.com/, which includes an unplayable browser game as well as a timer which counts up every second.
