The Switch has sold 15m as of now. Assuming it can reach 17m by March, it may take a year and a half to reach XBOne numbers. Pokemon and Animal Crossing would do the trick, plus whatever other seller Nintendo can get their hands on. The XBOne has no bigg system seller on the horizon (at least not as big as the Switch ones), but there's the chance they surprise us. Around the 2nd half of 2019 we'll see the Switch outselling the XBOne, if everything goes on as usual.
The 3DS will take a while to beat, but I'm sure Nintendo have some redesigns up their sleeves for that. 2021-22 at best.
