Games like Pokemon Sun and Moon have shown there's still life in the old system. The 3DS is pretty cheap, and the 2DS is even cheaper, making the platform an ideal choice for young children. The future of Nintendo's business rests with the Switch, but for now it makes some sense to support the ageing 3DS too. Yes, it's possible the two will cannibalise each other's sales. But they offer vastly different experiences -- the Switch is a far more powerful console, and doubles as a capable home system. It's clearly aimed at an older demographic (most Switch trailers have focused on twenty and thirty-something hipsters), one with a little more disposable income.
