Guerrilla Games fokuserer helt og holdent på Horizon-serien, stadig, men mange savner fortsat Killzone-serien, og higer efter enten et nyt kapitel eller bare remasters af de klassiske spil.
Spørger du dog komponisten bag de velkendte scores fra netop disse gamle spil, så er der ikke rigtig et marked for førstnævnte, men måske for sidstnævnte. I et interview med VideoGamer siger komponist Joris de Man dette:
"I know that there have been petitions for it. I don't know if it will ever happen. I hope it will because I think it is quite an iconic franchise, but also I think it kind of has to take into account kind of the sensitivities and the shift in, I guess, what people want because it is quite bleak in some ways. I don't know if people have moved on from it and want something. I don't know sometimes I get the sense that people want something a bit more casual a bit more quick."
Det er endnu uvist hvad der kommer til at ske med Killzone, men det er efterhånden mange, mange år siden at vi sidst så den i aktion.
