What I find amusing is when they revise estimates after Q3 and still miss. They're entering a slow season, most of the sales are behind them, and they still miss guidance.
Think about it, they adjusted the forecast for 3DS just 3 months ago to 13.5 million. They came in at 12.24 million. But they were sitting at 11.65 million when they amended the forecast! So of the 1.85 million they projected to ship in the final quarter, they shipped only 0.59 million, or 32%. They were 68% off, entering a slow quarter, with retailer orders presumably already in the system.
Either they're bad at forecasts, or maybe they're just lying. Take your pick.
