Was the Xbox 360 really a huge success? It came second or third in sales for its generation of consoles. 75 million units in seven years is a small number compared to mobile devices. Android sold 144 million devices in Q4 2012 alone.

I think the next generation of consoles are going to struggle against cheaper systems like OUYA and tablets.
