Sure. 

What an amazing thread. The original poster makes two false claims (A and B) and everyone who responds to the thread just goes along with it.

It would take...
1. Getting close to current Xbox and PlayStation consoles in specs while also being easy to develop for (the easy to develop for I think is settled, the specs won't be due to the hybrid nature that's sure to stick). Switch 2 might be moderately underpowered in docked compared to Series S. No way is it touching Series X or PS5.
2. Robust online. Nintendo lacks most online features that have been the standard since Xbox 360 in 2005.

And even then, Nintendo games would still get a lot more sales. Nintendo players overwhelming come for the Nintendo games. PlayStation players come for a handful of Sony games usually and most of the sales are third-party. Xbox players might get a few Microsoft games on average, as they mostly play them on Game Pass.

The Switch has already seen third party sales improve dramatically compared to their last few systems, just through offering an appealing platform on which to play them.
Witcher 3 or It Takes Two or Yakuza Kiwami may not be high resolution or 60fps on Switch, but you can't take your PS or Xbox on the bus with you.

I think most just ignored that part, and answered what it would take to grow 3rd party adoption rates on Nintendo.
Which seems to be the essence of what hes getting at, rather than debate how close he is with A) and B).

The essence of what he's getting at is "I read something in another place, what do you guys think about it?", which he should be known for by now.

Your second post in this thread is awful, by the way. You said B might be true.

3rd parties won't prioritize Nintendo systems until they are as easy to develop for as other consoles. XB gets tons of 3rd parties because it easy to develop for not because the market is bigger than Nintendo. I don't think Nintendo will ever go for something easy, they like to stand out especially for their 1st party games.

this is my post:

I basically wrote that "while it might be true", as a I can't bother arguing that part.
And the rest of it is.... the software sales amounts aren't that big between them (which is ultimately all that matters).
Over last 4 years, switch had between 160m-230m sales pr year in software. While on PS4+PS5, they are much the same, just abit higher reaching upwards of 300m+ instead. 

This is not a "in 1 quarter does PS sell more than nintendo does lifetime" posting by me (as OP claimed).
So I'm actually saying the opposite.

Your take away is "You said B might be true." ?

This is false.

The stat was rather that 80% of Nintendo's software revenue comes from their own games.

Third party sales were about 50% of all Switch software sales as of two years ago:

When something is blatant bullshit, you don't begin your response with "this might be true." But let's just put that down as English not being your first language.
