Due to the success of the original Dead Space, a sequel was inevitable, especially considering that EA was the one behind the game.  Well, earlier this week EA made it official.  Dead Space 2 will be released for the Xbox 360, the PS3, and the PC.  No time frame was given though.

Isaac Clarke, the protagonist from the first game, will be returning in the sequel.  EA promises that the sequel will contain new characters, weapons, and environments.
