When it comes to hardware sales, Nintendo usually doesn't fail. From the smash success of the DS line, all the way back to their roots with the NES and even some of their more unorthodox hardware. It's hard to think of a Nintendo console not doing well.

Though Nintendo has a history of discontinuing its older consoles without missing a beat, there's reason to believe this won't happen with the Switch.

Here are four things to know about the Switch: As of late September, Nintendo had sold 146 million Switch machines since the gadget’s launch in March 2017. That makes it the third best-selling console in video game history behind Sony’s PlayStation 2 and the Nintendo DS.
