Would you be willing to answer a few brief questions about PlayStation Forums?
Just Playstation 4 netowork.
I'm pretty sure the developer can implement it from the start, so it's possible and I think some games have already said this is going to happen (War Thunder?). That being said, I'm almost positive that IW said that Ghosts would not be doing this.

If they did that there would be no reason to buy a PS4.
