I think people get confused by seeing "Sony wins the month!" But they ignore how well everybody was doing and that Nintendo and Microsoft make up a lot of lost ground in December. So 11 months of hearing Sony likely "winning" and yet being told it's not some sort of blowout.
Indeed.
I mean despite PS4 taking so many months of the year the gap between PS4 and Switch for 2018 is tiny. Small enough that it's still possible Switch outsells PS4 for the year. Same with Xbox One, it's been in 3rd place pretty much all year, but has had great growth and is extremely healthy.
None of this is taking away from PS4s tremendous performance this year, it blew away mine and most peoples expectations. But a lot of people simply focus on the leader or who's "winning" NPD months and not looking at how healthy the whole market currently is
