In the article itself, however, there is no mention of a PC release;
"Under development at EA Redwood Shores, Dead Space is expected to ship in Fall 2008 for the PLAYSTATION®3 computer entertainment system and Xbox 360™ videogame and entertainment system. This product is not yet rated by PEGI or ESRB. More information about Dead Space is available at www.deadspacegame.com."
I'll try and find out more for you, if I can.
