According to the recent Gamepro Magazine, Dutch developer Guerrilla is coming along in their development of Killzone 2. According to the magazine Killzone could appear already in September of this year.
Killzone PS3 in September = Incorrect
In the latest issue of GamePro magazine, they said:
"Killzone has been confirmed for a September release. Considering what we saw, gameplay-wise, at GDC in March, I think pushing this incredibly hyped and anticipated FPS out too early is a mistake, but it will sell like chocolate-chip hotcakes even if it’s another partial turd like the first."
Here’s what Seb “motherH” of Guerrilla Games had to say:
"That is incorrect. I don’t know why they would think this. Killzone for PS3 is not being released at that time."
