The Nintendo Switch was released in 2017, and the PS5 was released in 2020. As the PS5 prices drop because it gets older, the sales increase as customers take advantage of this.
This is what happened with the switch, and how Nintendo's sales got so high. So as the PS5 prices drop, the sales exponentially increase.
Not only are the sales going to surpass the Nintendo Switch's if given enough time. Playstation's net worth is almost double that of Nintendo's. Making Playstation the more successful company no matter what arguments you make.
Xbox is also a runner up to Nintendo.
