People should remember Nintendo still is going to sell about 90 million hardware units this generation in a fairly weakened state.
People still buy Nintendo hardware.
The issue they have with their software teams divided and modern development being far more complex, they can't satisify the software needs for two distinct platforms any longer.
That and the larger part of the Nintendo fanbase doesn't have access to what are generally their best games (Mario Kart 8 is better than 7, 3D World is better than 3D Land, Splatoon coming, etc.). So their bigger games end up selling to the smaller portion of their fanbase ... another issue unified platform would solve.
Smartphones is a bigger issue to Nintendo than Sony/MS.
