I think you fail to see that the companies in question are not charities. I also think you fail to see that Nintendo only has games while the other two companies can rely on more successful sectors allowing them room to screw up and lose money.

It seems that you like this particular belief because they are stomping the "compitition". I'm pretty sure you wouldn't care much if MS or Sony was doing the same thing. Understanding business and making money is a skill not chance. Nintendo has clearly showing skill and market understanding. Just remember understanding a market doesn't mean listening to it. It means understanding the actions of what the consumer does not what they say.

Its a fair point, when people are struggling to feed themselves they are going to care if a luxury item reduces in price.

The reality is that while the economy is bad, its not at that point yet. And importantly, Nintendo has VERY inelastic demand, they can charge double and it wont affect sales.

Their chosen businesstrategy isn't selling products with pricecut in mind (although, Wii was relatively cheap to begin with), the strategy is about perceived value of the product (content in this case).
It's unlikely that pricecut would help Wii in Japan, since there's virtually no competition in the new audience group and PS3 is selling just as good as Wii (ATM) for the core audience with double the price.

You had a fair point with not affording one, even if you'd want one, but i don't think it's an issue of not affording it. Judging by the current data available, it's more likely about the lack of killer software. As we've noticed, the right games sell anything in Japan and now we should wait what WM+ and WSR can do in the market and what kind effect Monster Hunter has.

Just out of interest, has Nintendo managed to reduce its manufacturing costs of the Wii dramatically at all since release. I'm not knocking the console but it did use proven mature hardware when released so it was both reliable and cheap, the downside there has to be its harder to reduce costs to a degree. Have they ever done a shrink on any of the components?

I really don't see the point of a Wii pricecut right now, perhaps over the holidays but they just need more great software out, thats all.
