According to Credit Suisse analyst Koya Tabata, the cost of manufacturing a Wii console has gone down by 45%. If this number is accurate, that would mean each Wii sold is bringing in nearly twice the profit as in previous years.
And yes, the Wii most definitely brings in profit per sale, around $6 USD each actually. If you take into consideration exactly how many Wiis have been sold worldwide, which is estimated to have just hit 50 million(!), the number can be quite staggering.
It's probably safe to say that Nintendo is not feeling the same financial pressures that other companies are in these trying times, so you have to wonder exactly why the company is putting up the trade cost of the console in the UK.
Maybe Nintendo just doesn't like the British?
