I don't think anyone expects PS5 to be anything other than the worst selling PS console in Japan in both hardware and software. Playstation is on the decline in Japan as Nintendo is set to continue its domination of the country. Though this launch/holiday period has so far been beyond abysmal for the PS5.

I wonder if in the next few years we'll see Japanese-centric third party games move from Playstation to the Switch and later Switch 2 as it really doesn't make sense to make big huge AAA games geared toward the Japanese market exclusively for a system that is probably only going to sell at best 8 million systems in the country when the Switch will likely top 30 million.

It depends. It would be ridiculous if Dragon Quest 12 didn't prioritize the Switch/Switch 2.
Final Fantasy? Hard to say. Square has committed to PS5 for FF16, I can't see that changing for FF17 very easily... Maybe if Dragon Quest sells something like 6M+ on Switch.

If Xenoblade Chronicles X2/3, or whatever Monolithsoft's next project is, sells ridiculous numbers on Switch, FF17 might be on Switch 2 or 3.

imagine Xenoblade 3 selling more then FF16, at least in japan, finally proving mololyth's (former square devs) vision for final fantasy was the correct one lol

Damn this Switch's sales from last week nearly equaled the PS5's lifetime sales numbers....

Lifetime

I thought PS5 would have at least one title in the top 30. Ouch.

• Momotaro is going to make Konami the 2nd place publisher for the year
• PS4 will probably end up with only 13-14 titles in the Top 50 this year, since a lot of games on the Switch outside the Top 30 continue to sell
• With three weeks left, I think we will see something in the region of 22.5 to 23 million sales within the Top 50

Damn not even 1 PS5 title in the top 50. This holiday is pretty damn tragic for PS5 in Japan.

There are not yet enough PS5 in the open to even have enough install base to get on this list yet. There are 172k PS5 (I'm leaving out the discless version since those can't contribute to the software numbers) and you need ~65k sales for a game to appear on the top 50, which would ba an attach rate of over 30%. Even for Nintendo titles, 30% are a lot and very hard to reach, so it's even more difficult for any other brand of games.

I'd look again in 3 weeks, at the end of the year. By then, the install base should have increased to an amount where a PS5 title technically could show up - but it would still be very difficult considering how slow the PS5 software sales seem to be so far.
