This news, combined with a previous Edge report stating that "one major Sony-owned studio has now ceased PlayStation 3 development, its entire focus having shifted to the console's successor," could point to the tantalising prospect of Guerrilla Games working on Killzone 4 for PlayStation 4.
The Sony-owned studio announced some time ago that it is working on a new IP, which is also discussed in the magazine.
Killzone 3 launched earlier this year, scoring a highly respectable 8.5 from IGN. A PS Vita version off the franchise is also known to be in development at SCE Studios Cambridge.
Thanks, Gamerzines.
