I reported a few weeks ago about Obsidian researching for the game. Well the guy who gave away those tidbits also has a blog in which he'll give away details on the upcoming game. No new info at the moment, just some amusing Alien comics.

Fascinating.
I guess you'll have to keep an eye on that for any new info.
