It would seem so, as Guerrilla Games are already hiring folks for, guess what: Another FPS title. I’m not complaining, though, Killzone 3 is my favorite shooter this generation.
The firm is looking for an “expert knowledge and understanding of current multiplayer trends both in First-Person Shooters as well as Online/Multiplayer in general.”
We don’t know what it is for sure, but Guerrilla Games are a competent bunch.

Considering the popularity, it isn’t a matter of if KZ4 comes out, it’s when.
Agreed.
I’ll give it go.
This could be great news….
Lets hope they revert back to the 2nd one as a basis for the online multiplayer as IMO KZ3 was a total turnoff compared to Killone 2!
not KZ4, for their new IP.
ive heard rumours there going to be working on a new vita game.
i hope its a psv and ps3 cross game like ruin is.
thats so cool, being able to play it on the go, then come home and pick up where you left off on your ps3!
only if vita let you connect the device to the TV and play it on there, then it would be the perfect device!
id want to be for 400 bucks though!
