JohnLucas actually turned out to be really accurate. He had been predicting since 2005 that the Wii was going to be the leading console. In March 2007 (when he joined I think) he predicted that the Wii would lead 360 sales WW by the end of July.
So he's like what, 1.5 weeks off? 2 weeks off? pretty impressive if you ask me. professional hurricane forecasters predicted an above-average season this year... yet there hasn't been any hurricanes at all, right?
and @kber.... i don't think he UNDERestimated 360/PS3. i think it was simply that he OVERestimated Nintendo's Production capabilities, haha. There weren't enough Wiis produced to make his forecasts come true.
