Nintendo had a very cheap to manufacture console, selling like hotcakes with an inflated price, and selling tons of wiimotes+nunchucks as it was used a lot as a party console. Add to this the huge number of non discounted ever games sold by Nintendo, so it's not comparable.
PS: And they had another moneyprinter, the DS.
Maybe Sony needs to change their strategy then. That was my point.
They got it half right this time though, with PS4. The Vita is where they failed.
