Destructoid asked Inafune how he felt about Mega Man being in Smash Bros. He gave them this response.
"I'm really happy for that! It's great! And hopefully they'll put Yaiba in it in the future!"
When asked about Yaiba: Ninja Gaiden Z coming to Wii U, here's his answer.
"Yeah, no, not right now."
You know what I'm pretty sure about? I'm pretty sure Nintendo would never include a character in Smash Bros. that has never had any representation on any Nintendo platform.
