I don't even know if its so different as it is doubling down on their strengths. Portables are Nintendo's strength, every single Nintendo portable has outsold it's console counterpart by a minimum of 50 million units every gen since the Super Nintendo/Famicom.
3DS - 65-70 million vs Wii U - 14-15 million
DS - 150 million vs Wii - 100 million
GBA - 80 million vs GameCube - 22 million
