There's a chance we may be seeing a Killzone 2 release as early as September. Game Planets is reporting that the latest issue of Power Unlimited magazine states that "expectations for the PlayStation 3 premier shooter are high, and Sony aims to release Killzone 2 during September."
While we're going to reserve judgement for now, we wouldn't be surprised if this was true. We first got a glimpse of the game two years ago and, judging from the way Sony is handling the Killzone 2 presentation at E3, they must have something spectacular to show us now. A pre-Halo 3 release would also do the game a great deal of good, especially if its as groundbreaking as they say.
We'll keep you updated as and when any developments occur.
