Nintendo should stop making consoles. That's the most expensive, least profitable, and least interesting thing they make.
They should swap to making platform agnostic peripherals and unique games to go with it.
So instead of going out and spending $250 on a Wii, you'd spend $50 to get a Wiimote, Nunchuck, sensor bar, and a download code for Wii Sports, for example, and it'd work with any computer, console, phone, etc.
Because the white box and disk weren't interesting - just (relatively) expensive and underpowered.
Instead of just making games for iOS and Android, Nintendo should be making hardware that connects to it so you can transform your iPhone into a suped up GBA, that comes with a real game bundled with it.
Having said that - I'll probably buy the Switch and I'll probably be happy with it. But it seems to me they could have just made the Joycons so that they connect to your phone instead of to their own proprietary tablet that they have no profit margin on.
