PS4-1520k
NSW-1195k
XBO-1125k

Holidays is going to be massive they managed 6m for Nov+Dec last year, should manage at least 7.5m this year.

However looking at how things are going my prediction of 18m globally in 2018 might be looking a little high now.... With an 8m Nov+Dec they'd still have to average 272k per week for June-October to end the year with 18m...

XBox One is starting to find some traction in non-holiday months ... the XBox One X has been a large boost for them, think mid-gen hardware refreshes are basically going to become the norm now.

YOY %'s :  (from ResetEra MagicPork)

PS4: +19%
Switch: +1%  (its still not down from last year)
XBox One: +33%
3DS: +17%

Best selling Software:
God of War, Detroit: Become Human, Donkey Kong Country: Tropical Freeze and Hyrule Warriors: Definitive Edition.

Even though they probably won't admit it, I think they were banking on Labo being a pretty big hit, just treading water until November arrives can't have been the game plan if they seriously thought 20 million was doable. 

Not a bad month for anyone, in fact pretty good all around.

Any idea of when we will get software sales? Since May did give us some exclusives like Detroit, Donkey Kong, Hyrule Warriors, and State of Decay 2. I'm very curious to see how all of them sold especially State of Decay.

I dunno... I think the Pokemon & Smash are kinda a letdown.
Its not the next normal mainline Pokemon game's, and smash looks like its some sorta Port with a few extra's.

Im not expecting Switch to have a unsually large holidays because of Smash & Pokemon, because of this.

Considering some recent statements made Reggie and Nintendo of France, I don't actually think this was the case. I think they really are betting big on Smash and Pokemon in November and December. 

According to Reset Era page, the best selling software was

1. God Of War
2. Donkey Kong Country: Tropical Freeze
3. Detroit: Becoming Human
4. Hyrule Warriors

Looks like DKC is really doing well.

First Party releases or releases in general? Because in general, the rest of the year has plenty of releases for the Switch to choose from.

6/22 - Mario Tennis Aces
6/29 - Wolfenstein II; Crash N-Sane Trilogy
7/13 - Octopath Traveler; Captain Toad
7/27 - Go Vacation
8/9 - Okami HD
8/28 - Monster Hunter Generations Ultimate
9/11 - NBA 2K19
9/25 - Valkyria Chronicles 4
9/28 - FIFA 19, Dragon Ball FighterZ
10/02 - Mega Man 11
10/05 - Super Mario Party
10/16 - Starlink: Battle for Atlas
11/16 - Pokemon Let's Go, Pikachu/Eevee!
12/07 - Smash Bros. Ultimate

Plus there are other games with 2018 release dates, but no specific date like Dark Souls: Remastered, The World Ends with You: Final Remix, Tales of Vesperia: Definitive Edition, and Team Sonic Racing.

In terms of First Party Nintendo titles, it is a little lacking for sure. But overall, the Switch in 2018 looks fine.

Also, don't fall asleep on Super Mario Party. That game could potentially sell big numbers. Obviously not at the levels of Smash or Pokemon, but it's an old-school, board-styled Mario Party!! Something that fans have wanted for ages and it actually looks like a lot of fun! That's a game that will attract both the young kids who want a fun Mario game to play and the adults who grew up with the classic N64/GameCube Mario Party games that have been waiting and clamoring for this kind of game for years. That, combined with Pokemon and Smash Bros. I think that combination is going to be pretty lethal in the holidays and I think it's enough for Nintendo to reach their goal.
