Realistically if they could claw back to even 33 million users (N64 levels) for the console
And say 50 million for the portable (down from the 3DS, but not bad considering every damn kid is obsessed with tablet/phone games from birth nowadays).
... that wouldn't be so bad. Nintendo could make a pretty nice profit at those levels considering how competitive the market conditions are nowadays I think they'd take it. Combine that with big profits from smartphone games and Nintendo would be back making "Nintendo like profits" soon enough.
But even this level of performance will require a lot of hard work from Nintendo, a willingness to change bad habits, and probably even on top of that a little luck with new IP or something new.
