Pokemon Sun/Moon is performing worse than Smash Ultimate did last year. If we don't see a major boost due to the recent announcement it will only sell 25K in the next 4 weeks bringing its total to around 650K for the first half of the year. Smash sold 779K during the first half of the year in 2019. It will be interesting how DLC and Expansions affect Pokemon's legs going forward. 

• Smash Ultimate (first half of 2019) - 779.845
• Pokemon Sword / Shield (2020) - 619.825

It's a gradual transition.  You can look at the top 30 games that Marth just posted.  Switch has 7 third party games and PS4 has 6.  Switch already has a slight lead.  That gap is only going to grow as PS4 gets phased out.

Next Week Animal Crossing NH will be the 10th JAPAN's BEST SELLING VIDEO GAME of ALL TIME..

NINTENDOMINTES THE JAPANESE TOP TEN BEST SELLING VIDEO GAMES of ALL TIME once AGAIN

And then the third parties will start making switch exclusives? Yeah I doubt it. Switch will continue to get multi plat of smaller titles but in no way will it ever dominate. Also It makes 0 financial sense for third parties to make switch exclusives 

I don't get it either.  Sony home consoles have been averaging 1 billion+ games sold for the last 25 years, 85+% 3rd party but NOW is the time they will be shying away to make Switch exclusives that have shown not to sell 3rd party software anywhere near that.

PS4 install base will be lucky to get to 10m in Japan, and PS5 install base will likely be even less.  Switch install base will be 2-4 times that.  It really makes zero financial sense for a third party to release on PS5 unless it has a significant Western market.  Everything else will be on Switch, or at the very least multiplat.

How many of those 1 billion games were sold in Japan?

Japan isn’t the be all end all for most games. Being exclusive for any platform doesn’t make sense until someone paid them to make it. The switch still doesn’t get big third party games so I don’t see how you expect exclusive titles to start coming. It hasn’t even gotten a monster hunter yet

Actually it is.  Most third party games made by Japanese studios are made with the Japanese market it mind.  There are actually quite a few games that never get localized outside of Japan, and even the ones that do often have Japan as the primary market.

Japanese third party games are mostly made for the Japanese.

Big third parties games aren’t targeting just japan anymore. That explains why they aren’t on switch 

Yep.  The few big third party games will be PS5 only or multiplat.  Switch will get a version of everything else, either exclusive or multiplat.  Switch will have most of the third party games.
