its just got outsold by 60k in February, what makes you think it win? not to mention ps4 had a monster holiday that year.
A comprehensive analysis of the numbers. As in, which games go with the numbers listed in the OP.
Switch has had no new releases that drove hardware sales in 2018 while the PS4 had multiple new releases that drove hardware sales in 2015. Since Switch is beating the PS4 despite the lack of new games, it's looking good for Nintendo's console.
