Nintendo 3DS has had a solid run since its debut in 2011. In seven years, the handheld (and its extended family of varied 2DS and 3DS models) has sold over 72 million units and over 364 million pieces of software. Given that Nintendo Switch can function as a handheld, though, you might think its record-setting first year would mark the end of Nintendo's support for 3DS, but that doesn't appear to be the case.
During a presentation to investors, Nintendo discussed their continued commitment to the 3DS brand. Nintendo first highlighted upcoming 3DS games that have already been announced, like the re-releases of Captain Toad: Treasure Tracker and Luigi's Mansion. After this, Nintendo promised even more support, stating that they are in the process of developing games scheduled to launch "in 2019 and beyond." Looks like 3DS is here to stay for at least a little while longer.
