Playstation's Official Magazine has publicized the latest and greatest rumor: Killzone 3 is in development and will release sometime in 2010. In the latest issue, they call it one of Sony's "secret games of 2010". According to the same publication, Killzone 3 is "deep into development" and will hit the shelves sometime within the next year.

This is a conceivable rumor, despite the fact of it being a rumor. The last title, which took nearly 5 years to develop and create, sold great on the PlayStation 3, and many knew that a sequel was imminent. Guerrilla now has a strong game engine and multiplayer composition, so less effort is required from the developer itself.

KZ3 is not the only major rumor that they mentioned, though. They also noted a probable sequel to Treyarch's Call of Duty: World at War, and how Resistance 3 was in the works.

Killzone 2 was one of my most favored shooters this year, definitely a first-class runner up to Operation Flashpoint: Dragon Rising, and a sequel would be delightful.
