All i can say is that from most of the reports i have seen Nintendo has fulfilled its promise of shipping 6 million Wiis by 31 of March. The speculation that Nintendo are or are not sitting on stock piles of Wiis is irrelevant. They never promised more, so why should anyone expect more? They are the ones losing out if they lose customers because they are unwilling to ' release' these supposed stockpiles, so the only one this will really hurt is Nintendo.
Could they be sitting on stockpiles of Wiis? Very likely, after all the circumstances, Japanese stock sale (?), the ending the fiscal year, Corporate bonus for performance kicking in, Wii should be easier to manufacture it is entirely plausible that Nintendo are hoarding Wiis. But to complain after they fulfilled there promise (ie 6 million by end of fiscal year) is silly.
If anyone should be put under the spotlight its sony, they claimed that they too would have shipped the same number of consoles by the end of the fiscal year and have fallen well short of that goal. Why are people not complaining about this?
So Nintendo fulfills its promise but gets blasted, and sony fails and is unscathed?
Just an interesting observation - Not a blast at anyone
