I think the hype for Switch will taper off after Xmas 2018. This is not a Wii rocket,
so 2 Xmas' of good sales is about enough for the hype.

Then with a couple of big PS4 titles due out in 2019, both Xbox and Switch will have trouble matching sales next year,
especially once the PS4 price drop hits, I'm guessing November 2018.

I suspect by either Tokyo Game Show in September or PlayStation Experience on December we'll have release dates in
2019 for Last of Us 2 and Ghosts of Tsushima, helping sell the lower priced PS4 next year.

Xbox basically have to forget this gen and just focus on hitting the next gen, with Xbox 2, running full speed!!
No more TV, TV, TV, bollocks, just quality 1St party AAA titles from day one and evenly spread so they each sell well.
They desperately need 1St party titles that show off the power and capabilities of the Xbox 2. Non of the game trailers shown at E3 this year
filled that need, IMO. They looked good, but didn't have the extra polish.

Slight problem with that theory, Nintendo has several big games set for 2019. Fire Emblem is a rising star, and let us not forget a new Pokemon Game.

2018 has holes, but 2019 has the tentpole game to beat all tentpole games. 

Also Yokai Watch 4 is getting more info dropped soon, 23rd I believe. That will move stuff in Japan. 

Outside of splatoon 2 they haven't had much that appeals to a large japanese audience yet. A new Pokemon game, yokai watch, animal crossing, a new monster Hunter could really make the switch blow up in Japan.

In the WiiU/3DS or Wii/DS era Nintendo seem to split their development between handheld and console. I'm not talking 3rd party support, what i'm referring is Nintendo's internal studios they should all be making games for one platform now and help with the Nintendo drought that plague past console.  I think PAOerfulone did a good job listing all the game that are coming to 3DS, what I don't get is why aren't these game also being ported to the Switch. 

As someone that doesn't care for Smash this year E3 was a big let down, I'm looking forward to Fire Emblem: Three Houses but that's Q2 2019. 

Mario Tennis Ace is another shitty kid version, I wish they would bring back Mario Tennis GBC & Mario Golf GBC formula; Tennis and golf with RPG elements. 

In light of the recent NPD numbers for the month of May, adjustments have been made.
Unfortunately, all 3 systems were adjusted down. PS4 by 22k, Switch by 31k, Xbox One by 33k. Not too drastic, but still down.

June 9th Numbers have been added. Same ol' song and dance.

Anybody else thinking Switch could be somewhat undertracked? I mean, sales still haven't caught up to the shipments until end of March, I can see 5-8 weeks worth of supply in stores and transit, but we're already at 10 weeks now.

That doesn't mean that I think that the current numbers are very off, just maybe some couple thousands here and there since early this year, which adds up after more than 20 weeks

It's possible, but it wouldn't be much, like somewhere between 5-10k each week. They were recently adjusted down because the May NPD had the Switch just slightly overtracked in the US for the month of May (as well as the other two) and Japan is essentially spot on since we get new numbers every Wednesday from multiple sources (Media Create, Famitsu, Dengeki). So if it is under tracked, it would be in Europe and other territories. 

Yeah, US and Japan are set as you said. Europe and RoW however, not so much, and I think some more have been sold there as VGC is tracking. I also don't think it's very much (200k max) like I said before. Just a hunch, we'll see more in a month with the next quarterly results.

Agreed.
