Notes: Roughly speaking, there is a console game of sorts in every three or four years, but a main series game hasn't appeared for Wii U or GC, despite the plans for one in GC.

For handhelds, there has always been a game of sorts for every two to three years, with each handheld having two or three games.

This gives us this rough perspective:

4. 2030: Switch suc. 3
5. 2033: Switch suc. 4
6. 2036: Switch suc. 5
7. 2039: Switch suc. 6
8. 2042: Switch suc. 7

Handheld consoles:

1. 2018-2019: N3DS Suc.
2. 2020: N3DS Suc. 2nd game.
3. 2022: N3DS Suc.2 .

13. 2042: N3DS Suc. 7
14. 2044: N3DS Suc. 7 2nd game.

Be careful, however, as Kirby remains a filler franchise, and not a big seller for Nintendo. Because of this until it gets Fire Emblem treatment, it will remain mismanaged.
