Still depends on how much the Switch will share with PS5/XSX, how much they will compete and how much time Switch has left. If it gets replaced a year from now it was 8th Gen, but if it lives for like five more years as Nintendo’s primary system then it was 9th Gen. Obviously this debate will be even funnier if it lives for another three and a half years, making it relevant just as long during the 9th Gen as it was during the 8th Gen.

I consider it 9th gen.

Why is this important?

a 9th gen system, plays 9th gen games.
Hard to argue against this one.

Will the Switch (current model) get: (and play/look at simularish levels?)

Call of Duty - Cold War
Assassin's creed - Valhalla
Cyberpunk 2077
Battlefield 6
Monster Hunter - World 2
Destiny 3
Final Fantasy 7R - part 2
...
..
.

Even then it would still be a 8,5 gen or something imo.
You could also argue that its still competeing against the PS4/XB1 after the PS5/XSX launches :p

Yeah, in fact that would quite literally make the Switch a “Gen 8.5” console. However do we acknowledge in-between gens? In any case it wouldn’t make the question any easier.

Your last sentence is true. Then it depends on how Switch is positioned and what kind of games it still gets.

If Switch is able to get the majority of next gen big AAA multiplats 3rd party titles, and they look and play at respectable levels.
I ll eat the crow that follows.

It will be one when it surpasses PS4.

Some may ask, "Why is this question important?"  It's importance depends on how you define generation.  If generation is based on a systems power and specs then it's not an important question, because it's obvious which systems have similar specs.  On the other hand if you define generation by which systems are competing, then it is an important question.

The PS5 will launch later this year, and then both the PS5 and PS4 will be on the market at the same time.  Will these systems be competing?  No, not really.  They are not in the same generation.  A PS5 customer next year will want to play the latest games at home, the games showed off at Sony's recent presentation.  A PS4 customer next year will be looking for a home system that is a value, a cheap system with a huge library of older games.  Even though they are both home systems, they aren't competing because they are in different generations.  PS4 was competing with the Wii U though.  Those systems were in the same generation.

So the key question is, "Will the PS5 be competing with the Switch?"  A person who wants to play the lastest games at home might buy the PS5.  This same person also might buy a Switch.  Animal Crossing: New Horizons, Pokemon Sw/Sh, and Smash Bros Ultimate are also the latest games.  You can play all of these games by hooking your Switch up to a TV.  The two systems will be competing, because they are both the latest home system.  Sure, Switch is portable too, but Switch can easily appeal to someone who only wants to play a home system.  Since both PS5 and Switch will be the latest home systems, then they will be competing.

I think what is throwing people is that the Switch seems so different.  Several years ago a person might have said, "Blockbuster and Netflix aren't competing because they are just so different.  Netflix isn't even a store.  It just rents movies through the mail.  Blockbuster is in the video store market, and Netflix is in the video by mail market."  Fast forward a few years and it's R.I.P. Blockbuster.  They were always competing, because what customers wanted was to watch videos at home.  Both were providing this same service, but they approached it in very different ways.

Switch and PS5 are both going to be the latest home console system for their respective companies.  They both are making an appeal to home console gamers, but they are coming at it from two very different ways.  Customers are still going to see them as fulfilling the same role, just like they saw Blockbuster and Netflix as fulfilling the same role.

Because Switch and PS5 are the latest home systems for their two respective companies, they are in the same generation.

No need for crow, it probably won’t be.

WiiU, PS3 and Xbox 360 were the latest home systems from their respective companies in 2012, they were not in the same generation.

Switch will be about 3.7 years old when PS5/XSX launch. Are we to say Switch had zero contemparies for it's first 3.7 years? Nah.

 - Number of games shared between Switch and PS4/XBO will be higher than PS5/XSX.

- Launch date of Switch is closer to PS4/XBO than PS5/XSX.

- Power is closer to PS4/XBO than PS5/XSX.

- If Switch successor launches before August 2024 than more of the Switch's life as the most recent console will be alongside ps4/xbo rather than ps5/xsx.

This whole debate will blow over in a few years anyway, and history will remember the Switch as an 8th gen console. It already says as such on Wikipedia. Generel consensus is what matters, and on a forum such as this there's always going to be a larger amount of people viewing it as part of this new generation than there is in the general public. Yet even here of all places the poll is split.

Do this same poll in a few more years and I guarantee "no" would be the overwhelming winner.

Do you think people in the public are really thinking that the 3.5 year old Switch is part of the "next generation!" that all the mainstream news outlets they read are talking about?

10 years from now Switch will be remembered alongside PS4/XBO becuase when your average joe gamer thinks about the next generation right now, they are absolutley not thinking about the Switch being part of that.
