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.
Well the thing is only nintendo games will really sell nintendo consoles thats always gonna be a problem. second point is ps4 in 4 week period beats switch by over 60k, the momentum is in ps4 court right now.
