4 PlayStations in the Top 7 is nutty.
Nobody is shaking Sony from dominance again in the console market next-gen.
That console market lockdown and hold is stronger than ever.
That's why this generation was quite literally the worst generation to screw up as badly as MS did. With the advent of digital sales and services, had MS got their heads out of their asses, they could have continued from 360 to Xbone and crushed Sony. Of course they didn't and the rest is history.
