PS3 dev kits weren't given out to third-party developers from the get-go, same with the PS4 dev kits. And at least not for free. By the time they had the option for adding PS3 compatibility, they were too far along with the Xbox 360 version, and likely did not have enough time or development money to port it to the PS3.
