The studio's gaffer, David Cage, has revealed that the platform holder has earned his "loyalty".
Speaking with CVG, Cage said that Quantic Dream's relationship with Sony "has been fantastic" and that the studio will continue pumping out products to support the PlayStation brand.
"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.
"I am very loyal in general - or I try to be. I know that trusting me is always a big risk and when people do, I feel like I owe them something. It's not just because I want to thank them, though. 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."
Cage wouldn't reveal whether Quantic Dream is involved in Sony's shared technology programme, but did reveal that the studios are talking all the time.
"We talk to Naughty Dog, Santa Monica, Guerrilla, Media Molecule - all these great studios," he added. "We talk about technology, best practise, how we do things - we share experience and expertise. I think that's of real value for everybody."
Cage added that he'd recently collaborated on a modern PS3 first-person shooter that "isn't Killzone". Intriguing.
It's heart-warming to see Cage so happy with his studio's position in the PlayStation family, and he already feels like a pivotal part of the brand to us. We can't wait to see what he does next.
