a feature like a game capture card where u can record everything on the screen and save it to memory unit a option to record gameplay in full quality that can be turned on and off through the ps guide menu i think this would be a very popular feature for the people who do game commentaries like if you want to do a game commentary you just connect the mic you want and put it in commentary mode and start recording then you can move to computer with file sharing with console and the best part it would be free other then buying a capture card that may have bad quality or a bunch of wires when you can have one simple device
