But you said there is a huge amount of overlap from Wii and DS owners. For that group who owned both (50 million? 60 million? 70 million? 80 million?), it doesn't matter if its one or two devices... they bought a lot of games for both devices.
And about the 13/14 years: the biggest part of these games was sold in a much shorter period: 890 million DS games and were sold in a six-year-period and 840 million Wii games were sold in a six-year-period, so 1730 million games in total.
