It's been downhill ever since the N64 as far as I'm concerned. Eschewing the young adult market in favour of kiddie stuff and skipping the CD-ROM revolution was a major blunder that lost this former Nintendo fan forever.

As for the Wii, I was surprised when it did as well as it did. I turned out to be right and wrong. Wrong about the Wii itself, which did well - but right about Nintendo's overall fate. Let's face it, the Wii was a fluke.
