My interest in Dead Space just went up several notches!  I hadn't really paid this game too much attention until I watched the new trailers.  Wow!  This game looks amazingly creepy, especially the "Lullaby Trailer" with the revised version of Twinkle Twinkle over the quick, gruesome cuts.  Of course, they were cut by the director of the movie Saw, and the influence is definately obvious.  If they can maintain the scare factor for the full game I will be super excited to play this one.  Dead Space has just landed on my radar in a BIG way.
