Just like the Wii, the 5th best-selling console of all time? The console that outsold all other consoles of its generation, except the Nintendo DS?
The assumption that those many new gamers would behave like a "core" market was laughably wrong.
As for the portable, Nintendo is the best in the game, benefited from being up against Sony (the worst in the mobile game... they practically assassinated their own platform), and they have the benefit of a built-in market at home.
The Switch isn't a DS... it's not a pocket gaming platform. It isn't as useful as an iPad. It's as powerful as a console. What is it exactly, other than some kind of massive compromise rendered on substandard hardware?
Edit: left out the "isn't".
I would like an excuse to come back to a console, but so far this isn't it, for me.
