Why are they all down so much compared to last year?

Damn, I somehow missed that this thread had been posted already.

I remain confident Switch will eventually out-leg the Wii due to Nintendo basically abandoning the latter prematurely after just 4 years of support.

Switch leaving 3DS in the dust, and deservedly so, it is a vastly superior product.

The most important thing to note is that 3DS sales rate had already peaked well before this 33 month point. Meanwhile Switch sales are currently accelerating. Lifetime, Switch is going to easily blow the 3DS away.

Conservatively, it will definitely sell at least 100m.  But I actually think Switch still has some major surprises left.  

Switch has almost no third party exclusives yet, even though the 3DS had a lot of third party exclusives.  Because of that I think there are a lot of third party exclusives still one the way.  All of these 3DS developers are actually working on Switch games right now.  A good example is Bravely Default 2, which was just announced.  I thought games like this would have been here sooner, but apparently going from the 240p 3DS to the 720p-900p Switch is going to prolong development time a lot.  It's a big adjustment.

Right now most third party games are ports or indies, but I think Switch has a much richer third party library in its future.  That will lead to much greater lifetime sales than 100m.  It won't just be first party games carrying the Switch almost single handedly.

I dunno, that would require third parties to pull their heads out of their collective rectums and invest in the platform, something I just can't see happening, with Switch nearing its third birthday and the likes of Activision and Capcom still treating it like it's the Wii U.

I am not talking about AAA games.  I am talking about 3DS sequels and the like.  Like I said, Bravely Default 2.  There are a whole lot of development teams that made exclusive games for 3DS, but we haven't seen similar original games for Switch yet.  I believe the lastest "Layton" game is actually a 3DS port, for example.  Where is the brand new Layton game?  It's still in development.

We just now got an announcement for Bravely Default 2.  This is the first taste of the games I am talking about.  They have been in development for a while now, and we'll probably start getting games like this in 2020.  I suspect these games take a long time to develop now, because it is a huge leap in technology to go from the 3DS to the Switch.  

Right now Switch is selling well based purely on 1) Nintendo IP, 2) third party ports and 3) indie games.  We are about to get a fourth leg of games to the Switch 4) third party exclusives.  These will mostly be from handheld developers, but it will be original content!  These new third party games mean that 2019 will not be Switch's peak year.  Switch will continue to get content from it's first 3 legs, while getting new content from the fourth leg as well.

I wasn't necessarily thinking of AAA games either, I'm just not seeing enough evidence of this supposed oncoming wave of third party exclusives to have confidence in its existence. I don't think third parties have the guts to make that kind of investment in the Switch. They're still burying their heads in the sand and ignoring its success for the most part.

Clash of the Titans.

The DS really shows that Nintendo systems can have Playstation-like legs. Hopefully Switch also demonstrates this.

Now this is an exciting battle; back and forth without one clearly beating the other. That's one hell of a jump for Switch though, gaining 3.3 million in one month.
