I talked to EA about this integration of PB in Hardline as well as BF4. They told me that PB would be in the games, but they will be replaced by FairFight when FairFight is fully integrated in the games. This is because that there have been some problems with PB and EA can't really communicate with PB. So to say, they do what they want to and will not cooperate with EA in the way EA had hoped they would. I was told that the communication between Fairfight and EA was much better.
The guy I talked with didn't know when it would happen, but he didn't think it would be long before Fairfight would stand for most of the cheater/hacker systems. Which is nice, because as I've seen Fairfight on the in-game-chat's it is really a realle agressive software.
So I'm looking forward to Fairfight taking the control.
