agree. I wonder how much system rsources sony uses for its OS and eye.

From the rumors right now: 2-CPU cores, 2GB RAM (extended to 2.5-3GB of the swap if the Game are not using this RAM).

The games that use the Eye will use the Game resource to handle it... so that's the big difference between thsi can and Kinect... for example you can use the Voice Recognition while playing game on Xbone but not on PS4... you need to stop the game to OS handle Voice Recognition again... so OS is using Game resource to make this happen but it can use Game resource just when no game is running.

So you have two scenarios here...

No game running: You can use the Eye/Voice Recognition anytime while you use the OS.
Game running: Eye/Voice Recognition for OS is disabled and you can use them just if the Game support it.

Game is the priority App for everyting in PS4... OS just can use GPU if no game is running... more CPU core or Memory is only used by OS if no game is running (except memory that have a ~1GB reserved for swap but Game have priority... if a game is using this part the OS can't touch it but if the game is not using the OS can use it).

I think I convered everything we know about this subject.

@Bolded: More guessing.  Where has Sony confirmed how voice navigation will or will not work.  Where has Sony stated you have to completly leave a game in order to use the PSeye which makes no sense if you can use it before going into a game.  How is Sony OS switching between its game and App OS and how do they accomplish this task. Why reserve 2 CPU cores if not to run something like the PSeye within or outside of a game.  If the game is the top priority, then there would be no need to reserve any CPU cores.  You could use the Arm chip to save the state of the game and release the CPU and memory at that point.
