I wouldn't say dropped out but rather reinvented what a video game console is.

Guess I just thought it was one of those things that gamers mostly agree on. Like:

Nintendo is innovative

Sega was ahead of their time

Enix ruined Square

PlayStation is the biggest brand

EA can eat a dick

Guess there are other factors to consider.

Agree with most of those, Nintendo I feel is the "bigger" brand when you take hardware and software into consideration because PS is really propped up by 3rd party games right now (CoD, RDR, FIFA, Madden, etc).

Just take a gander at the top 20 games of 2018:

(If you combine Let's Go it is at 7,294,966 good for 6th)

The majority of people buying the PS4 don't buy it for PlayStation games and that is the case for the last 2 generations, so Sony's position is very fleeting (just ask Microsoft after they fell HARD).

Anybody made that board of things that will kill the Switch?

Well they consolidated both their home and portable efforts into one system. Which is an impressive portable and a less impressive console Because Nintendo really intended for it to continue their portable Legacy. The Switch Lite drives that point home. Nintendo really left the strict home console bussiness after the Wii U flop.

This is 100% untrue

2014 (PS4/XBO first full year)

PS3-3.6m

360-2.6m

2015 (PS4/XBO second full year)

PS3-1.3m

360-0.9m

They basically died as soon as their successors launched.

Absolutely I agree. The Switch is not a home console, it is a mobile system with a dock. Nintendo did drop out, sadly, and so high sales of the Switch need to be considered vs. the DS and 3DS etc., Nintendo is actually selling less hardware. Here's hoping the Switch success gives Nintendo some confidence to re-enter the home console market. I think they could do a very good job with the new style of hardware that the Switch pioneered.

For example: nVidia and ARM, no optical drive, no hard drive, just 1 or 2 cartridge slots. They could easily release a 7nm GTX 1660 Super based system in 2020 for $250 and I think it would sell really well just like the Wii did (would be faster than the Xbox One X).

The release of PS5/Scarlett will not harm the Switch any more than the release of a new luxury sports car will hurt sales of motorbikes. The last two and a half years clearly show it coexists with dedicated consoles without either stealing sales from the other.

Ah, the old chalkboard, I remember that one. 

Some suggestions for it:

"Not powerful enough"

"No games"

"Too expensive"

"Won't get the big AAA multiplats"

"No multimedia features"

"Used up all it's big IPs already"

"PS5/Scarlett"

What do you consider "impressive" for a console? Because I can say that I have had more fun with the Switch as a console over as a handheld.  I get what you're saying but to dismiss the appeal of the Switch as a console is very short sighted.  It would take more than one bad console for them to abandon that or else we wouldn't have had the Wii after the GameCube... And as a console I find the Switch lineup better than what Xbox/PS offer right now (Marvel Ultimate Alliance 3, Zelda: BotW, Mario Odyssey, Pokemon Sw/Sh, Smash, Mario Kart, etc.)

2012/13 sales were still strong is what I meant as far as yearly years (announcement/release year), sorry for the confusion and that was a typo with per year, meant to say that final year.
