Quantic Dream seems to be hard at work with their upcoming game for the PlayStation 3, Beyond: Two Souls. It also seems like the French developer is also working on a game for Sony’s next PlayStation if their registration of the SingularityPS4.com domain is to be believed.
The developer is known for registering domains for game’s they are currently working on and as the PS4 part of the domain pretty much guarantees it is for Sony’s next home console.
This could be a title based off the Kara tech demo shown by the team. At the moment there is no information beside the domain name and the fact that it is for the “PS4”.
