In a recent interview with SCEA's Peter Dille, Killzone 2 is mentioned briefly as one of Sony's upcoming titles to release in the second half of 2007.
"I think we have a good first half of the year. Games like Lair that people are really excited about. MLB is coming out and is looking great and is the best-selling sports game from a first-party studio. Motorstorm. Heavenly Sword. And don't forget you have games like Killzone in the back half of the year. We're not really saying that there is one game that consumers have to wait for. I think that the content is there now and the content is coming. It's going to be a steady stream of really great PlayStation 3 content," stated Dille.
