I was waiting inside a match, map Okefenokee as JSF turn 18 if you want the details, and my PS3 lost all bluetooth connection. Both of my controllers lost connection to the system and could not reconnect and my headset could not connect either. I had to reset the entire system to get it working again.
Twice before my controller was disconnected while playing endwar but I was able to reconnect shortly, I waited about a whole minute this time and the bluetooth did not come back on.
The first two times it had happened was on the main menu and then on the main ToW sceen.
Never happened to me before outside of this game.
