1.N does not hold the rights to bayonetta to best of my knowledge
They may not own the IP, but I have little doubt that if they're paying for development then they own the exclusive publishing rights for Bayonetta 2.
As for the folks wondering if they would publish it on other platforms, my guess would be no. If it did see a multiplatform release, my bet would be they'd cut a deal with another publisher to sell them the rights to publish the game on other platforms for a set royalty per sale, rather than do it themselves since Nintendo probably doesn't want their logo popping up in games on other consoles.
Either way, I don't see it as likely. I'd say the best chance it has of happening is if the game is not a financial success (which I honestly think it won't be on that console) and Nintendo wants to get as much money back from it as they can. But Nintendo are generally not hurting for cash so they could afford to say screw it to the whole idea and eat the loss instead just to make sure they keep an exclusive.
