The only one we can get a good idea of unit sales is Switch because there is only a single price point and its the exact same as last year.

PS4/XBO get harder to determine since they have different priced versions along with various discounts.

Hopefully MagicPork pulls through and leaks the numbers again.

Yeah,Mat confirmed it was by revenue.

Ofcourse xbox one X helped, but its not mainly because of it. Matt mentioned that fortnite is the biggest reason xbox one is selling double and also slightly helping ps4(probably ps4 would have had bigger drop this year without it). I dont know how he knows this, but he said it :P.

Crazy to see MLB The show 18 still going strong and Detroit top 10 :o. State of decay 2 had pretty massive drop.

There's no fucking chance XB1 X isn't having a large impact on hardware sales, revenue doesn't magically double, Fortnite is on every system.  Mat also clarified the Fornite hypothesis is more conjecture on his part than anything else. 

Well the revenue metric does skew things.  The X is 500 vs the S at 300 (plus discounts).  Still a healthy boost though.

I think the Pro and X have done well.  Though I think the X benefits greatly from Microsofts  frankly tireless efforts to improve the public image of Xbox.  Will be interesting to see if the Xbone can finally crack the 10mil mark worldwide this year.  Iirc, it has never crossed that mark.

June was a very impressive month for switch, i guess E3, gamestop promotion, and fortnite gave it a nice boost. ps4 is also very impressive, last year it sold around 220k, don't know what's going on this year in june and why hardware is so much higher, industry seems to be thriving.

Fortnite is likely helping across the board. Mid-gen refreshes are helping PS4 and XBox. God Of War is helping PS4. More inventory is helping Switch and an older buyer base is why you are seeing sky high Switch software sales (more disposable income than kids).

Mat said something interesting about Fortnite on PS4:

'So, given current trends, slate, pricing, marketing and the Days of Play promotions that were happening around E3, I was expecting a bit more growth on PS4 than we saw. There are massive challenges with trying to determine the impact of an individual causal factor like Fortnite on the sales curve that covers a territory the size of the US, particularly when looking at monthly data, but I've been doing this for a long time, have built countless models, and can run the math. And, given all those factors when comparing to performance of Xbox One and Switch, I'm seeing the impact of Fortnite being much more meaningful on the sales of Xbox One and Switch than I am on PS4.

Could be lots of reasons for this. PS4 has had a significant number of big releases in recent months that would make Fortnite less meaningful overall by rising the base demand curve. I may not be properly gauging just how strong June was for PS4 last year (since we're looking at growth and all... maybe I'm not properly taking into account base and incremental sales of June a year ago which is throwing off my expectations now). Perhaps the PS4 has been doing so well for so long that even higher growth than we're seeing is a completely unreasonable expectation.

The data certainly isn't perfect (monthly at a total territory level is incredibly difficult to do this kind of work with and carries a massive range of error). But people asked for my take given what I see so I gave it. People can disagree, because the data is certainly nowhere near conclusive.

As for cross-play, well, I don't think cross-play has anything to do with performance at all. I do think the account locking thing is an issue, particularly when it comes to Fortnite, where people want to play with whatever items they've acquired wherever they wish to play. If someone wishes to play Fortnite on Mobile, PC and/or Console, and doesn't really care about any other games, then the account locking issue on PS4 could be a purchase barrier. It's one of the reasons why I think we've seen such big boosts to Xbox One this year, and why Switch did so well in June. But if people disagree my feelings certainly won't be hurt.'

I thought PS4 did like 380k last year, not 220k.

The God of War effect + hype for Spider-Man and Last of Us Part 2 from E3 I think are the key reasons why PS4 took June.
