Also if this is a handheld first, console second machine, whyin the WORLD have Zelda Breath of the Wild - the most console-centric game Nintendo has made in ages - be the flagship launch as opposed to Pokemon or Mario or one of their other more in-between games like Kart? Why on earth use BotW, which people will just plain NOT want to play on the go?

Which is why, according to this article, you can attatch it to your TV. So that you aren't required to play on the go.
