The next Killzone is set after the events of Killzone 3, according to a Siliconera source, who would not comment on whether the game in question was related to the Killzone project for PlayStation Vita.

Sony is reportedly recording a teaser (trailer?) for the upcoming game, which contains the following dialogue, as voiced by a woman with to a Helghan Autarch:

My sons and my daughters, today we take the first step toward our imperial future.

For years, this once-great nation has stagnated in the shadow of its enemies. Governed by scoundrels who flaunted the ideals established by my father, these traitors… these enemies of our race have diluted and exploited the triad of Duty, Obedience, and Loyalty.

This regime, this corrupt regime, has been dissolved. In its place does rise an era of stability and strength. A time of opportunity born from a promise that we shall return our people to their proper sphere of dominance.

Whatever the teaser, we take it we’ll probably see it at E3 next month.
