This graph shows the best possible way to compare the PlayStation 4 with the two previous generation consoles.
The image is from Twitter, and it shows how well did the Xbox 360, the PlayStation 3, and the PlayStation 4 sell. Of course, the PS4 doesn’t have as long of a life as the two other machines yet, but still, its sales performance is way above the other consoles!
That’s not all: if we add the PS3 and the X360 sales (!), then this result pops up. The PlayStation 4 is just barely above the sales of the combined PS3+X360 figures. There’s no way not to commend Sony’s results.
Perhaps this graph could be proving them right in targeting no less than one hundred million sales for the PlayStation 4!
