There have been many comparisons drawn up with the Nintendo Switch and the 3DS handheld console. This is because both consoles feature touchscreen controls and can be played in handheld mode. This is extra true with the Switch Lite that has been designed specifically for handheld gaming.
However, one of the unique features of the 3DS is its included stylus which can be used to play certain games, but now it looks like that line between the Switch and 3DS is about to get blurrer. This is because in a post on the ResetEra forums, it has been discovered that Nintendo has an official stylus designed for the Switch that will be launching later this year.
