Yaiba: Ninja Gaiden Z isn't even out yet, but Team Ninja head Yosuke Hayashi let it slip, in a talk with Keiji Inafune, translated by Siliconera, that the company will come out with a new, more traditional and fan-friendly entry in the series.
"Team Ninja is thinking of the next Ninja Gaiden," Hayashi explained. "For example, if the games were food, the Ninja Gaiden series would be a rich meaty entree and Yaiba: Ninja Gaiden Z would be dessert. Every course of the meal would be in the same Ninja Gaiden world, but gamers will experience different kinds of play. That’s how Yaiba: Ninja Gaiden Z will be different."
Yaiba certainly looked appetizing when the first screenshots were loosed, like a more cleaned up Killer is Dead. Unfortunately, every single thing else about the game that's been shown off has been embarrassingly bad. Even if it plays well, I don't know if I could stomach that sleazy cheeseball performance.
