Your estimates are very silly. Xbone can go up to 75m? PS4 up to 165m? 25-50m range for the WiiU?? Very laughable. PS4 wont outdo PS2. The Xbone will lose marketshare in the US and UK, it cannot do anything close to 70m. 360 will end up selling around 90m, I expect the Xbone to lose around half of the marketshare.
WiiU 25m minimum? Lol more like 15m is gonna be it's maximum, it's selling ~3m a year.
