One thing that appears to becoming more of an issue for the big three gaming consoles is the Wii ability to make dollars for parent company Nintendo.
According to various published reports Sony will never make money of the sale of the Playstation 3 console. Even worse is the fact Microsoft loses money on every unit that is sold. The theory is that they will make money on games and other ways.
But the Wii makes money for Nintendo on every unit. Plus at $249 average street price the Wii is an affordable purchase for more people. The hard core gamer community is not driving Wii sales.
Certain features of the Wii make it more attractive to the new gamer which is a vast untapped market. The second controller, Wii Nunchuk, is a great design feature. That is one of the reasons why the Nintendo Wii has sold over 43.75 million units compared to to 26.49 million Xbox 360 units and 18.82 million Playstation 3 consoles.
