Sony already fired on all cylinders this generation. If they manage to win next gen, it will only be the second time in history the preceding winner is also the succeeding winner. I don't like those odds but, who knows.
Thats one weird way of looking at it. playstation has dominated the home console market 3 out 4 times. The gen that it lost was because it made hardware that costs way more then its main competition 360, while running multiplatform games much worse, and releasing a year later, actually a year and half later in its strongest region europe, missing the crucial holiday period. ps3 was a massive fuck up, and still sold near 90 million.
