There was a walkman in peace walker that Big Boss could use. They just said it was a prototype.

Yeah after rewatching the video I figured that Big Boss is there to get Chico and Paz. I'm going to assume that other Peace Walker characters will be making a return as well like Amanda, Strangelove, Huey (Otacon's dad), Cecile, and Kaz Miller.
