Quantic Dream boss David Cage has said the French developer is "staying exclusive" with Sony for the present and foreseeable future.
Sony published the studio's last title Heavy Rain last February for PS3. Its previous publishers include Atari for Fahrenheit and Eidos for Omikron: The Nomad Soul.
But Cage says it's all Sony from here on in for now.
"We have an exclusive relationship with Sony," he said, speaking to CVG.
"The relationship on Heavy Rain has been fantastic. They trusted us from day one, supported us all the way through. It was really a very risky project [for them] and they never let us down.
"Being a part of a company with what are probably the best studios in the world is something really pleasant for us. We're happy to continue this relationship and create content for the PlayStation brand. But they fund our projects, so we're staying exclusive to PlayStation."
Cage continued: "We have a relationship that works, we're excited by the platform - we think it's the best platform out there. We're glad to continue to work this way."
He didn't confirm if Quantic shared any tech within the first-party Sony Worldwide Studios, but said that regular conversations took place with studios like Naughty Dog, Media Molecule, Guerrilla and God of War developer Sony Santa Monica.
Cage, however, admitted he'd also been asked to advise on a modern FPS for PS3, but confirmed it wasn't Killzone 3.
Earlier this week, speculation on Quantic Dream's next title ramped up, with domain registrations for "PlaySeries" and "Fiv5" found.
