Yeah increased production... typically means increased sales. So a large drop would be strange.

So after 9 consecutive weeks of Pokemon S/V being #1 on the charts, it has finally been dethroned. That's pretty impressive actually. Which other game had that kind of streak? I know Monster Hunter World had like a similar streak.

Nah, MHW didn't have anywhere near that kind of streak. Animal Crossing NH would be my guess as to something that had a similar streak.

Actually AC:NW was dethroned by Final Fantasy 7 Remake when it first debuted.

Sure it dropped to #2 as AC:NW took back #1 the next week, but I'm talking about "consecutively" being #1 weekly.

Plus The reason I mention MHW is because of here

I looked up the media creates sales. Monster Hunter World had a 6 week streak.

PS5 console is currently at first place on Amazon JP. It has been like that for a couple of days, so it looks like the demand is there. With enough stock, Sony can have a good year.

What's going on with Xbox in Japan? I always see them in stock in my country why aren't they shipping them to Japan instead

Demand is there, only for hardware. Until Final Fantasy and Hogwarts, it seems.

Famitsu seems overtracker Xbox in Japan.
