It’s said Isaac Clarke will fight it’s way through a snow covered planet called “Tau Volantis”. The main mission will be to find the “codex” which is said to mkae it possible tre-mutate the Necromorph. At this point the hostiles are referred to as “The Hive Mind”. We have to wait for an official response from EA or Visceral Games about this but a new Dead Space would be more than welcome.

Electronic Arts is developing a new Dead Space game. No surprise there, but it doesn’t take place on a spaceship. Dead Space 3 is set on Tau Volantis, an icy planet where Isaac Clarke has to wade through white-out blizzard conditions.
 
Early in Dead Space 3, Isaac crash lands on the planet. He believes he may be the only survivor and makes his way to an abandoned waystation, which he uses for shelter from the snowstorm. There he finds a survivor who is severely injured. Isaac speaks to the near dead comrade who reveals there are other survivors that trekked off to another facility. One of them is Ellie, a key character from the original Dead Space game. Isaac grabs a snowsuit and heads into the blizzard.
