The PS4 has been doing better in Japan over the past two years but did you know that most recently, it outsold the Nintendo Wii U in terms of lifetime sales? Based on Media Crate Reports, the PS4 outsold the Wii U in lifetime sales in September.

From Media Create, after 2 years in the market, the PS4 has surpassed Wii U in lifetime sales.
PS4 – 3,267,243          Wii U- 3,265,329
Wii U launched in Japan about one year and 3 months before PS4.
Wii U launch: December 8, 2012          PS4 launch: February 22, 2014

Considering how Nintendo is releasing less Wii U games this year in Japan and that the PS4 is getting plenty of JP support in the form of releases like ATLUS’ and SEGA’s Persona 5, not surprising to see the PS4 outsell the Wii U in lifetime sales.
