At the recent Level-5 World Conference, it was announced that Namco-Bandai will be publishing the PlayStation 3 Ni no Kuni game in the West. Its official English title is Ni no Kuni: Wrath of the White Witch, and it is scheduled to be released in North America and Europe next year.
A collaboration between Level-5 and the renowned animation house Studio Ghibli, Ni no Kuni: Wrath of the White Witch for PS3 begins similarly to the unlocalized DS game, but soon expands into its own story. The magic book that came as a physical reference with Ni no Kuni for DS will be an in-game item in the PS3 version.
Here's a new trailer for Wrath of the White Witch. Sorry folks, it's still in Japanese.
