Some people say that if you deduct the DVD function from the success of the PS2, the success of the PS4 would be higher than that of the PS2. So even if the PS4 doesn't reach 155 million units, the success of the PS4 alone could be more valuable as a standalone console. I think there's something real about it.

Thats like saying Xbox360 only reached 85m+ units because of ~30m Red Rings of Deaths, killing the console.

No, that's actually not the point of it. It was more about a thesis that claimed that an estimated 130 million PS4 sales were a more remarkable success than 150 million PS2's. At the time of the release of the PS2, the first DVD players were enormously expensive, which is why several million units of the PS2 were supposedly sold off due to the DVD function alone.

The PS4, on the other hand, offers no added value, relative to today's standards, than the one to play.
