That's because the PS4 is pushing 6 years to the NS 2+ (it not at 2.5yrs yet) and still somehow only managing to be only like 13k behind the NS.
I am sorry but there is more to take away from that than the fact that the NS is "winning" the week which should be expected considering the age of the consoles.
We should also account for the Switch having not one but two imminent announced revisions as of these numbers. Context matters, I get that, but the responses here act as though PS4 won the week. The reaction frankly seems disproportionate to the results.
