Don't get me wrong, I do love Kirby and Yoshi. I just think both franchises don't see a lot of drastic improvements. Perhaps we are spoiled with how Mario and Zelda were re-envisioned. When I looked at the announcement trailers for Kirby and Yoshi I just thought: "That looks and plays just like the last iterations on the Wii and Wii U". The mechanics are very solid and fun, and I really love them both, but at some point it gets stale. Now it makes sense both franchises are not made for open-world designs but I think it would be interest if both games will try at least to do something completely different. The same goes for the New Super Mario Bros. series, great series but each entry is basically the same yet with solid improvements.
It is almost 2018, developers need to think broader. Super Mario Galaxy was already a great example of how to think broader ten years ago. Super Mario 3D World was great too, but it lacked the scope of the Galaxy games. And every Zelda game couldn't go wrong except for Skyward Sword. A Link Between Worlds proved that even the Zelda series could break free from traditional conventionals which started a new bright future for the series.
