A developer diary for Yaiba: Ninja Gaiden Z is below, and features Team Ninja leader Yosuke Hayashi and concept lead, Keiji Inafune, discussing development of the game. The game is in the works between three developmental entities: Comcept, Spark Unlimited, and Team Ninja. In the video, Inafune and Hayashi talk about many things, along with the differences between development in Japan and the west – something which has been touched upon before by the team. Have a watch below. We’re still unsure of a release date or platforms, but we’ll know more come E3 next week.
