If the NX doesn't come out in 2016, where will the "Nintendo-like" profits come from?

Even if the NX comes out in 2016, R&D for the platform will be costly.

The games schedule for 2016 is somewhat sparse for Nintendo platforms, as it seems the only real heavy hitter will be Zelda, at least from the games announced so far. An open world Zelda will also be extraordinarily costly for development and simply doesn't sell that phenomenally well.
I think Zelda U port and 3D Mario are almost certain for NX launch in 2016.
