Why is there Yo-kai Watch Jam: Yo-kai Academy Y - Waiwai Gakuen Seikatsu? Didn’t it launched in August already?

Momotaro and AoC holding strong

Nice to see Sakuna get a decent sized restock on COMG, still in 2nd place on the eShop. In Japan the game is probably sold >100K digital on the Switch alone.
Hope they are able to ship a decent amount of physical copies for the holidays.
Expecting Marvelous to reveal 1 million shipped + digital pretty soon.

COMG underestimates Fit Boxing 2, as usual games like this don't do that well on COMG. 

Also not related to this chart but that's a really solid hold for Momotaro. If Famitsu echoes the ~15% drop then it will easily outperform my 3rd week expectations for it.

Sakuna on Switch got more stock it seens.

Has COMG declined in the years we've been following it, has it always had multiple games with only two preorders on the charts?

To be fair, in the past there were normally two more systems for software to be on. The loss of the portable Sony system and dedicated home Nintendo console means there's less software overall. That has led to a pretty sizable loss in terms of the number of retail packaged software titles released.

Well, after that brief interruption of Sony games it looks like SK and Taiwan are back to being all Nintendo.

It's not only the Japanese market, the all Asia market will take over by Nintendo. In the US , Microsoft and Nintendo are strong. Left Uk, Italy,  Middle East, and Latin America for sony major dominance. France and Germany Nintendo have a good portion too. 

Not much movement right now...
