Some like to say Sony gets "arrogant" when they're on top, and will try to make a case with the pro's features/lack thereof...but reality is Sony is playing with house money, and enjoy a 1 yr headstart to boot. Whatever MS does in '17, even if its an upgradeable console, will be answered with PS5 in 2019 at the latest.
