Well actually I lie, the objective points are
1. PS5 tracking ahead of PS4
2. PS5 Software much lower

The meaningful part is what sales would actually be if everyone who wanted a PS5 in Japan could get one, how many PS5's would there be staying in Japan and what would software sales look like then. No one has those answers.

and sonys poor treament is not exclusive to Japan, Spain and other EU countries had weeks where there were more PS4's being sold than PS5's.

Year 2050, PlayStation fans, while reminescenting the long past presence of PlayStation consoles in Japan, parrot to each other the idea that the cause of the decline was solely due to the form factor so that their hearts can rest at peace.

When someone dared to pointed them out that in 2020 Nintendo's first-party software alone accounted for more than half of the packaged software sales in Japan they responded at unison: "hardware! hardware! hardware!".

Form factor is important but so is software and Nintendo is smoking everybody else in Japan which is the real reason that the pattern we are seeing in Japan isn't replicated in US, even though Switch is wildly successful there too.

It has to sell 6mil first and that’s not even guaranteed. Also sales for PS5 this year will be under 1mil for software. Take that as you will with your 50mil prediction 

I dunno what this is supposed to mean, but the year is still 2021 and Nintendo is outselling every possible system in Japan, and also the US and sometimes Europe. Also the Xbox Series X is more powerful.

I really hope that Sony is planning to improve PS5 availability in Japan during January and February. I’m hoping it’s some kind of strategy where they focus on other regions during Christmas, but make up for it a little bit by increasing shipments to Japan during January and February to generate some momentum as Elden Ring and other games that appeal in Japan get close to arriving.

Oh yeah, the Sony decline that started with the PS3 but Nintendo users think it started with the Switch.

Well if you want to count all sony consoles in japan it technically started with the psp

It always makes me laugh when people say that japan is handheld focused only and that japan would be back to Sony if they released a psp 2, when in actuality, even when Sony made handheld, they still sold less than nintendo handheld.

Point is, Nintendo is just more popular in japan then Sony is

Nintendo users? Or people with common sense? The decline happened but this is a much deeper decline and a bit different from the previous transitions

They always have been more than Sony, and since the Gameboy, Nintendo handhelds (Gameboy Advance the exception) have dominated Japan.
