The January 2015 NPD results show that the PlayStation 4 has outsold the Xbox One in the US once again. But putting competition aside, the group’s latest report also reveals that both consoles combined are selling remarkable well overall. NPD analyst Liam Callahan said:

“The combined hardware install base of PlayStation 4 and Xbox One is close to 60 percent higher than the cumulative hardware totals for the Xbox 360 and PlayStation 3 at the same point in their lifecycles (after 15 months).”

Speaking to Polygon, Callahan said that these numbers do consider the different release dates of the PlayStation 3 and Xbox 360. “It adds up the 15-month total for 360 (starting from Nov. 2005) and the 15-month total for PS3 (starting from Nov. 2006),” he explained. We’re also told that total software sales overall have increased by roughly five percent year on year, although current-gen software sales have increased by 74 percent in comparison to last-gen’s software sales decline of 36 percent.

Peripheral sales have also seen a slight increase of three percent as owners of new consoles pick up extra accessories. “Increased accessory spending for eighth generation console – gamepads as well as headphones/headsets – offset any seventh generation console and portable accessory spending declines,” said Callahan.

Did this result surprise anyone? Not me! Let us know your thoughts on the report.
