The Wii Fit prediction is just plain silly. Not quite as silly as the SSB:B prediction, though, or the 2008 sell through figures for the Wii. Who predicts that the Wii will sell 15 million units all year when Nintendo will be producing well north of 20 million assuming zero production increases?
I guess we're jumping the gun a bit, eh? Don't worry, if he keeps his scruples there will be plenty of threads just like this one posted by him.
