On the PS3 launch the console had production issues for those who don't remember or know these issues forced the EU release to be delayed by 4-5 months in order to sort the issue out, that's why the PS3 numbers are low.

That means there's a pretty good chance Switch still takes this week.

Yeah it has a shot. Depends on stock obviously..

Also, when will PS5 | Series X,S be added to the frontpage? and how will you split marketshare percentages? ;P

Comparisons with the launch of previous PS systems paints a truly sobering picture.

I know we can't extrapolate too much about a system's long term prospects from its first week alone, but I would be surprised if PS5 manages to reach/pass PS4 sales in Japan, which itself is likewise looking to fall short of PS3, which in turn sold less than PS2.

631k for the PS2. Is that a record? Either way, pretty sad to think about how far PlayStation has declined in Japan. The PS4 had a stronger launch and a better library overall than the PS3, thanks in large part to Dragon Quest XI, Monster Hunter World, Kingdom Hearts 3, and various other major Japanese 3rd party franchises that missed out on the PS3. Yet despite all of that, the PS4 will most likely finish lower than the PS3.

damn i flopped with 0% on xbox hardware, 10k units off

PS5 launch is where I expected it to land, software is worse but I hinted at this during the prediction league - scalpers, digital and no real heavy hitting game for the Japanese audience is difficult to overcome. PS5 software will be sluggish until Demon Slayer and Final Fantasy release on the platform, there aren't any other exclusives revealed so far that would really move the needle on the PS5. I'd be surprised if the PS4/PS5 ecosystem surpasses 1 million this year. Expecting it to end up in the 800K range, so the PS5 can be somewhere in the region of 200-300K by the end of the year. But seemingly no PS5 game will surpass 100K this year physically. 

So we'd be looking at under 15% software and 15% hardware market share for the PS4/PS5 this year, with Final Fantasy VII, Ghost of Tsushima, Resident Evil 3, Yakuza 7: Like a Dragon & The Last of Us Part II as their top selling games. Situation for the PlayStation is even more complex next year, as Nintendo is starting to receive both huge third party titles, AA exclusives and multiplats. If Final Fantasy is pushed into 2022, they'd be lacking any game that historically is probable to surpass 500K, relying on Demon Slayer being both a hit and pushing hardware. 

I am surprised it dropped 23k.

Switch was only 1.8k off to keep the lead.

Probably building up some stock for the HW:AoC and Momotaro releases this week.
