There's a difference in battery life too which is one of the main reason why they chose it over the lite. And in Japan they have been selling the switch without a dock for years now

As a Playstation fan, I am not the biggest fan of FF series anymore or Square Enix in general. Kingdom Hearts 3 was weak, FF XV was weak. I really like FF VII Remake, but nowadays I feel like as a PS owner I enjoy more Persona and NiEr. Maybe Japanese fans feel the same.
Many PS owners prefer Persona series now.

all the ps5 games underperformed in Japan.

Besides good hardware sales.

Switch has surpassed 9 million for the year across the Top 50 games, until September there are no games on the PS4/PS5 that will debut above 50K in Japan. While it seems that Switch will probably surpass 13 million software by that point. In the past 8 weeks there has been over 1.8 million software sold on the Switch the major software that launched was New Pokemon Snap, Miitopia, Rune Factory 5, Game Builder Garage.

Until the 8th of August we have Monster Hunter Stories 2, Yu-Gi-Oh! Rush Duel, Samurai Warriors 5, Skyward Sword HD, Baseball Spirits, Mario Golf: Super Rush, Ace Attorney Chronicles & Shin-Kun so by that point Switch would surpass 12 million software for the year just across the Top 50, while PS4/PS5 will likely go down to 350-400K as it doesn't seem that Scarlet Nexus is going to actually end up with a high debut. 

Top 10 Publishers

1. Nintendo - 3.795.089 (39.9%)
2. Capcom - 2.494.541 (26.2%)
3. Konami - 1.018.023 (10.7%)
4. Marvelous - 472.392 (4.9%)
5. Pokemon Co - 470.914 (4.9%)
6. Square Enix - 416.293 (4.4%)
7. Microsoft - 329.948 (3.4%)
8. Bandai Namco - 215.389 (2.3%)
9. Imagineer - 76.107 (0.8%)
10. Teyon Japan - 65.575 (0.7%)

Past 8 weeks:

• Nintendo - 848.195
• Capcom - 610.428
• Konami - 110.861
• Marvelous - 118.270
• Pokemon Co - 275.539

By early August we should be looking at Nintendo should continue in a steady pace and surpass 4.5 million; nothing that could be compared to New Horizon last year but third parties have picked up the slack. It's still a very strong year for Nintendo just won't be as strong for 1st Party games as last year especially without a big fall game, Mario Party Superstars is likely to be able to hit 1 million but nothing that's remotely as big as Pokemon Remakes.  Remains to be seen how Mario Golf, Skyward Sword, Metroid Dread, Warioware, Game Builder Garage, Miitopia, Bowser's Fury do long term. 

Last year outside of New Horizon the only new games were Clubhouse Games, Super Mario 3D All-Stars, Pikmin 3 Deluxe & The Origami King so without a major end of year game we are likely going to see Nintendo achieve a similar result compared to last year. It's 2022 when we will see the peak of Nintendo in Japan.

I do think Splatoon 3 will be the first 3 million physical launch of the Switch era, considering the user base will be close to 25 million by the launch it's very possible we would be looking at 5 million in Japan shipped at launch. Splatoon 2 was launched to drive hardware sales early into the Switch's life while the userbase was still at 1.19 million with digital the launch of Splatoon 2 was actually pretty close to the amount of Switches sold at the time. Also we've had 5 years since the launch so plenty of time to really ensure that they further perfect the gameplay. 

Secondly we have the follow-up to the Breath of the Wild, this will be the first Zelda game that could potentially have over 2 million sales at launch. Similarly to Splatoon 2, Breath of the Wild launched at a time when the audience was tiny compared to where it will be next year. 

On top of them we have likely other titles that could cause waves like Tomagochi follow up, & a follow up to Ring Fit(if they have stopped updating it), Ring Fit continues to be the best selling evergreen this year - so with further updates it could very well match last year's total. 

Now where we are seeing real growth is among third parties year over year; Capcom should definitely surpass 3 million with Rise, Stories 2 & AA Chronicles by the end of the summer. While Konami is likely to surpass 2 million due to Momotaro, Yu-gi-oh, Baseball Spirits. 

As far as other publishers, I guess Neos will be the one to look out for Shin-Kun has a lot of interest around the game and if WoM is good it's likely to surpass 200K this Quarter.

Atlus also got a big highlight at the Direct which means that Nintendo is pushing Shin Megami Tensei V very hard World Wide & Japan, it could very well be the first game in the franchise that surpasses 500K in Japan, WoM will be key.

I think we will see more games reveled for the fall by third parties that will accelerate their growth in a serious way YoY, nothing on the scale of Momotaro unless DQ III Remake launches this fall. Still the fact that third party sales are likely to see x4 or x5 increase Year over Year on the Switch is emblematic of what we can expect in the fall and next year as we head into the Switch's peak. 

Poor or not, Japan gamers don't care much about it, it's not like they have time for TV mode in the 1st place.

Nintendo holding the entire top 13 and 29 of the top 31 games YTD really illustrates its dominance.
It will be very interesting to see how games like Shin Kun, Monster Hunter Stories 2, and Brilliant Diamond/Shining Pearl perform later this year.

Summer will be mostly Capcom & Konami making big strives among third parties. The biggest third party games of the summer are seemingly going to be from the two publishers. Although it's still early I can see Yu-Gi-Oh with good WoM being the highest potential game of the summer, remains to be seen but so far Konami has been very capable and all their games ended up surpassing 200K on the Switch. 

There is still time for a few more titles to be revealed for August & September but at the moment there are seven titles I think will definitely have the potential to surpass 100K sales this year. 

Currently I think Shin-kun & Samurai Warriors 5 might leg their way above 100K but that would depend on WoM. Shin-kun is the one with the higher potential due to the hype surrounding it's reveal and it's strong position in Amazon.co.jp for the past month. 

Not sure if we are going to see any other third party game that's launching this summer surpass 100K. 

400K+

• Yu-Gi-Oh! Rush Duel (Konami)

300K+

• Baseball Spirits (Konami)

200K+

• Monster Hunter Stories 2 (Capcom)

100K+

• Shin-kun (Neos)
• Dragon Ball Z: Kakarot (Bandai Namco)
• Samurai Warriors 5 (Koei Tecmo)
• Ace Attorney Chronicles (Capcom)

We are likely going to see around 7 million software reached by third parties within the Top 20 by the end of September. 

I am happy to see Nintendo still on top

How about Shin Megami Tensei V?

Right now I'm confident it's looking like a 300K+ game, still WoM will be key on how high it goes Persona's best performance in Japan physically is 500K which to me seems like the ceiling but as we get closer to release we can better anticipate what the initial shipment would look like and how it's being perceived on Japanese social media.
