Not really sure what you were trying to show me...
Was it the succession of Zelda titles? Or the diversity?

If it's the diversity, Nintendo can do better.

I think what hes saying is they already are doing what you suggested.

They already did this formula since a long time ago so nothing new.

I saw that… multiple times! :D

I just wanted more diversity.
Of the 13 titles, 6 were ports (assuming Four Swords was new. If not, seven, seven, then).

The only two games that stand out of the usual Zelda feel are Hyrule Warriors and Zelda Picross.

It's long time for them to reattempt the side scrolling Zelda once again. There were so many great moves added to the series in Zelda II. Who knows what they could do to reinvigorate this series with some amazing modern design mixed with that old-school anomoly. Not calling for a remake of Zelda II; I want a brand new title with brand new dungeons and an interesting overworld. Not too sure about the random encounters, but maybe that should stay as well to keep the lineage between the two.

Because they have to support two systems at the same time but now, it can be like this:

2018: a remastered 
2019: a new 2D top down Zelda like A Link Between World 
2020: Hyrule Warriors 2
2021: another spin off like Tri Force Heroes
2022: another Zelda Picross
2023: a big mainline game

For the life of me i can't remembre what remastered Zelda game came out this year...

2019: agreed! It can be a more artistic game, btw.
2020: I can live with that
2021: Spin-off: Zelda inspired game (no, not the CDi games!)
2022: mainline game (it's 4 years after BOTW, i think it's enough time if they re-use the same engine)
2023: either a RPG or a remaster of an old handheld game (like the Pokémon Let's Go Switch game)

This is just an example. 2021: a spin off with multiplayer feature like Tri Force Heroes. Let Go isn't just a remaster, it's a full remake. 2022: mainline game only if they reuse the same engine, if they built a new engine then not sure it will take only 4 years.

Sorry, i meant remake, not remaster. I keep using remaster as an equal to remake.

Yes, a mainline game by 2022 will most likely use the same engine. 
But, it's not impossible for them to do something new. BoTW took so much time because of the transition to HD development (NMSBU took 3 years to develop!).

Let's see...another 3D zelda, a 2D zelda, port of skyward sword, HD Wind Waker, that handles the next four years right there if they do those, so yeah when you consider ports, spinoffs, etc along with new games one game a year is not overwhelming.
