Those PS4 numbers are grim indeed. I find it hard to believe that's all Sony could ship.

As Jranation points out, this is the series debut on Switch, while it has an established audience on PS4. 

Is there still hope for the PS4 to reach 10 Million lifetime in Japan?

Nope, might not even surpass the PS3, Sony is likely sacrificing production of it in order to make sure they can have as many PS5's as they can at launch.  

A slim hope, but one that's dwindling with each passing week.

It has 810k to go.

AC - 56,160 
RFA - 44,261

Obviously, AC has way more sales than RFA, but I'm still impressed that the legs of RFA are getting close to AC.  Also both are up WoW simply because more Switches were available.

RFA would sell 200k next week if Nintendo shipped it. RFA demand is so high, 2mil is a pessimistic prediction at this point. There is also the fact that numbers are missing as we have confirmation that Nintendo online store sold 150k copies by I think end of april

There are lotteries for both the Switch And Ring Fit Adventure.

When I worked at retail, we hated dealing with collector's editions.  The kinds of people who are going to buy the collector's editions are generally always the people who are going to buy the game at least within the first couple of weeks, if not day 1. The company I worked for generally didn't discount them right away cause they're dumb and don't understand gaming, but we were encouraged by our particular store to discount them after a couple of weeks.  Honestly, I should have just bought some of them for myself and hung on to them for a decade or two, but that would have been too smart.

I predicted that it didn't have a chance in February. Corona helped the PS4 a lot more than I thought though.
