While the PS4 is a virtual lock to become the third PlayStation console to reach the 100-million-unit milestone, its pace is slowing.
In announcing its results for the fiscal third quarter, Sony today said it sold 8.1 million PS4s in the October-December period with what it characterized as aggressive promotional pricing for the holiday season. That total was actually lower than PS4 sales for the 2017 holiday season, which Sony said was "in-line with our expectations for this sixth year of the platform."
"Although we need to be conscious of potential volatility in profitability due to the console cycle going forward, we are working to mitigate that volatility by leveraging the more-than 91.6 million unit $#@!ulative install base of PS4 to benefit from the new business model created by network services and add-on content sales," Sony CFO Hiroki Totoki said in prepared remarks.
