I guess for Nintendo honestly their main problem is without a Wii-mote type gimmick they can't sell console hardware for sh*t basically, they practically were giving the GameCube away by the end of its life cycle (you could get one with a free game for $99.99 IIRC).
If worse ever came to worse, they could just publish console games on the PS4/X1 or seek out a partnership with either one of Sony/MS and develop for one or the other exclusively based on whoever gave them the best sweetheart deal.
Sure that would be a bruise to their ego, but business wise in the end that would be an easy fix to most of their issues.
They could continue to make gaming handhelds for a while longer.
