It appears that Alone in the Dark 5 is in development. I was tipped off by a news brief at Gamasutra, and I found some confirmation at Boomtown (babelfish translation from French) that is a year old. Eden is a French developer Kya, a third-person Jak & Daxter style platformer, as well as V-Rally 3. This means that their parent company, Atari, has moved the project away from the previous developer, Darkworks (who recently finished Cold Fear. Hopefully there will be something to see at E3 about ALOD5.
