Frictional Games, the guys who developed the Penumbra series, are working on a new game called Amnesia: The Dark Descent. Unsurprisingly, it is survival horror, just like their Penumbra games. It is in its early development stages, and the (admittedly atrocious) title is still subject to change, but the game is currently scheduled for release later this year (summer, allegedly).
Their development blog has some interesting ideas regarding the design of video games, as well. Nothing novel or groundbreaking, but I found it to be an interesting read nonetheless.
