Lower than expected hardware shipments for the quarter. The reduction of the forecast to 17m instead of 17.5m means that Nintendo wants to be sure to meet the new goal as shipping 2.5m units in the final quarter is much less of a challenge than 3m.
The PS4 shipped 17.7m units in its second full fiscal year when it had a $50 price cut, so in the big picture Switch sales are still great as they are among the most successful consoles in history, but the result gets dampened by Nintendo's high initial forecast. Furthermore, the hardware forecast is the only one that Nintendo fell short on and after the underwhelming fiscal Q1 it was clear that something would have to give. Nintendo's choice was hardware units, so they are prioritizing a long lifecycle for Switch.
New software releases did slightly better than I expected, but evergreens did worse. Not surprising, because sales of evergreens tie in with hardware sales and those came in below my expectation of 10-10.5m for the quarter.
