I like my Kirby games just the way they are and I don't think they need to be drastically improved or re-envisioned. It's a cute little platformer that I don't really need to put much thought into to enjoy a good time. One or two new mechanics per game is fine with me, and the new enemy capture mechanic looks pretty fun to try out, combing powerups and stuff.
My unwanted/unrelated 2 cents: What I find interesting is that around the same time Platinum Games made Bayonetta/Bayonetta 2, they also made another game about a strong female video-game character protagonist: The Legend of Korra. The gameplay elements are very similar (combat and overworld exploration) to the Bayonetta games, but without any of the sexualization of Bayonetta. Plot problems aside, the game does a good job of using a powerful and well-written female protagonist without oversexualizing Korra. Although that may have more to do with what they were allowed to do based on source material and the target audience being much younger than the M-rated Bayonetta series.....
Kirby games are fine just the way they are. They fulfill the purpose of a game to me: it's fun to play. Kirby Air Ride 2 needs to happen though.
As for XC2, is this the new Fire Emblem? Regardless to say, I'm still going to get it.
I have to say, I underestimated just how anime as hell Xenoblade 2 is. Like a lot of people were saying how anime the character designs are and I was just kind of like, "yeah, I guess they are," but the more plot interactions I see, the crazier it gets. This isn't a complaint, by the way, I just thought it was funny.
So, Bayonetta 3 just got announced for Switch...
And the first two games are coming out too. Yay more games on the switch! I just hope that Bayonetta 3 is a bit... better in its representation, especially the cutscenes. Her being confidently sexy and how the camera poses her are two separate things, and she can be sexy without being objectified!
I'm still going to avoid it though. It's not really my kind of game!
Bayonetta 3 announcement, alongside the ports, the character in Smash Bros and the amiibo just serves to confirm the franchise is basically owned by Nintendo now

Eh ? Forbid sexy stuff is the opposite of women freedom. The very central point of feminism is women can do what they want, even sexy stuff if they want, but nobody forces them do that.
If a camera angle make people think of a woman like an object, it means there's a problem with our education and mentality rather than the content itself.
edit : to clarify, hide that would avoid problems rather than solve them. What we really need is people think that there's a real human with emotions and rights beside boobs and booty.
