At this point, we can safely say that the Switch shipment will fall between 17 and 18M for the FY2018...But I am very curious of the next forecast they will announce for the period April 1st 2019 to March 31st 2020. The Switch should be up from FY2018 but somehow I don't imagine them provocating again with a 20M or more...Even if the Switch should have everything on her side to reach 20M+...

My personnal guest is a safe 19M.

25M.Labo will explode very soon.

Knowing them they will most likely expect too much again. So I'll go with 20M.

Which is not crazy, after 2017 they only had 4 "evergreen" titles, now they have 8 like this which will maintain in the top 20 everytime there won't be new releases from SONY and Microsoft.

Depends on when Pokemon and Animal Crossing launch. If late, probably close to 17, if both in the next couple months then 25 may be too small a number...

Especially if they launch cheaper more portable switch same time.

Could the main Pokemon alone in begining of Decembre 2019 produce more sales than Smash + the 2 Pokemon remake + Mario Party ?

Most likely yes, it will be a new gen and a lot of people are waiting for it

18, but I think they will make 19 in the end

20M. Nintendo is bold like that.

And they will probably end up selling 17M-18M and drop their shipment projecting to like 19M around this time next year.

I have been thinking (and I bought shares with this in mind), that this next Pokemon would break every launch records since the creation of the video games.
The install base will be around 45M, it is large enough to do a 10M+ first week.
