And you expect this to go better next gen, when Streaming service join in the fray and the value of the PC platform massively increased though gamepass?

No idea if it will go better next gen. Depends more on Sony than the competition.

Bethesda games will be exclusive to Xbox and PC, that's the main reason why Xbox will grow in market share this gen. And neither Xbox nor PS5 will come close to beating the Switch in sales.

Here is an estimate (in millions) by region:

I've answered your request.  Now I have a request too.  You can criticize my numbers if you like, but you have to come up with a better argument than, "I just don't think it's going to sell that much."

There's been no confirmation yet that PS5 won't be getting the next Elder Scrolls, Fallout, Doom, Wolfenstein, etc. They'll probably be just timed exclusives on Xbox Series for the first 6-12 months.

I personally don't think it's at all guaranteed that PS5 won't outsell PS4. Sure, Xbox Series hasn't stumbled as badly as Xbone did so far, but Xbone inherited a bigger install base to begin with thanks to the 360, while XS has still hardly set the world on fire and has yet to prove it'll win back any marketshare from PS in the long run.

It is not pretty clear how far switch can go. I believe switch sales can go as far as nintendo wanted the console to go. A switch 2 can kill the switch consoles sales if nintendo wanted to.

PS5 will be front loaded compared to PS4. It depends on if Microsoft is able to get their X360 customers back. I can see that with their developer acquisitions. In year 3 or 4 in PS5's lifecycle we could say more precise if PS5 can beat Switch. But PS5 shouldn't be able to beat Switch's 4th year.

Illuminati alt confirmed?

A few years ago I was one of the people who believed that the Switch was not a direct competitor of the Xbox and Playstation... that said, my opinion changed.
Hypothetically, what happens if the first party games on Xbox and playstation continue to grow in number, quality and sales, so that both consoles start to have significant differential factors (exclusive games that can only be played on these platforms)? In this scenario, I can no doubt see the logic "I buy Nintendo consoles to play Nintendo games" also applying to Sony and Microsoft consoles.
Three consoles with differentiating factors that make them unique (Exclusive Games). Suddenly the three "boxes" exist in "blue waters", that said, would it be a case in which the "blue and red ocean" philosophy that brought Nintendo so much success reaches a limit?

I don't believe in the idea that Nintendo will always have a "special Blue Ocean" permanently. That said, if playstation and Xbox differ enough from each other, I can see Nintendo's sales being affected.

In a simplified and direct way:
Fewer people thinking "N + P or X, because P and X are practically the same" and more people thinking "X and P are so different, I prefer (X + P), I don't need N".

Will this affect the switch? I doubt it, but what about the next Nintendo console, will it live in a "blue Ocean"? I have my doubts.

No japan, no record sales.
