In Japan and North America
Naruto Shippuden: Ultimate Ninja Storm 4 was supposed to be released later this year worldwide, but Bandai Namco has just confirmed that it will be delayed into 2016.
At first, the company just noted a delay in Japan to February 4, but it was only a matter of time for other regions — this morning, it stated that North America will be getting the game on February 9. Europe’s release date is unknown at this time.
If they need more time to polish it, that’s fine. I enjoyed what I played from a preview build, and the visual style is mesmerizing.
