GameInformer recently managed to get an interview with Suda51 at PAX West 2018. He revealed that he would love to make No More Heroes 3, but he wanted to work on a small niche title first and I suspect he then wanted to see how it was perceived before he starts work on an ambitious new project.
“Yeah, I’d really want to,” he started. “Those kinds of projects are hard to think about when you’re deep into another game. But Travis Strikes Again is one part of the No More Heroes story, it’s not the end of it.”
