I agree that nintendo has a different business model, but I think there is significant overlap between the markets, in other words I would expect xbox sales and wii sales to be competing at least in part for the same dollars.
Or is it a documented fact that those that own a wii buy xboxes later on ?
If you are thinking in terms of making products at a loss just for the heck of it then you are no longer competitive, you're already on the way down, it's just that the ground is still a long way off.
I doubt that's their real perspective. But the eagerness with which a 6 billion loss and a 7 year losing streak gets polished away with 'in a few years we'll be in the black' is quite amazing. I wouldn't be too proud of that.
The way these things get spun we'll probably never know the truth though. Nobody seems to like to admit to failure, even when it is blatantly obvious to the rest of the world. Zune anyone ?
As for the Wii, it's a great product, but it is fundamentally a differet market and business model. Nintendo makes money on hardware sales. They have a low attach rate of primarily 1st party games. Microsoft makes money on royalties. Xbox had an unprecidented high attach rate with significant 3rd party profit sharing. Xbox LIVE is also a hearty subscription business.
