without Sony, someone would fill in Sony's shoes to be the next big thing besides Nintendo and Sega back then. We all know Sony Playstation and what it has accomplished through each generation but speculating what would it have been without Sony? Maybe Sega still exists, Nintendo still dominates and control the 3rd party games. or even a new player similar to Sony came into the picture or if that was even MS coming to the picture earlier and became the dominate force. who knows.
