A lot of the 3DS companies were still releasing games in 2016 like Pokemon and Fire Emblem. It usually takes 3 years to make a game so we should start seeing some acceleration in 2019. Also, some companies like Alpha Dream still have titles slated for the 3DS in 2019. We won't see a game from them until 2020 at the earliest.
