Nintendo shortages for the 2nd year in a row

I just don't get it. Nintendo should have fixed their supply problems
by now. Or is there really a phenomenal spike in demand that have
caught them unaware? Christmas 2007 already and the shops *still*
don't have enough stock of the Nintendo Wii? Surely they wouldn't be
manufacturing these shortages to fuck with us salivating consumers!
