If you listen to this Nintendo Power Podcast, at around 24:50, Bill Trinen confirms that Bayonetta 3 is coming our this year.
“Knowing that they mentioned of course, Bayonetta 3 is still in the works. Ehm, it's just it really helps to round out the library overall of what’s available on Switch, and of course, that’s another game that’s, maybe coming a little bit sooner than people anticipated, later this year.”
There's a lot of people that thought it would be next year before it would release. I was one of those that wasn't sure about its due date, I still am not despite was Trinen said. But if it's true, I imagine we'll get a massive blowout at E3 and it'll possibly be a holiday season title.
