Doubtful, PS4 did 370k that month.

I believe. At the very least, I'll be very dissapointed if it can't break 300k.

It won't even break 230k, you can quote me on this. nobody is gonna go run out and buy a switch for fortnite when its been out on every platform for months, not to mention they look and play much better, plus sony won't even allow you to use your account on switch. 

370k will be too much to beat. However, 230k ain't that hard to beat with the Smash reveal, Fortnite, Paladins, Mario Tennis Aces and a slew of third party titles late this month. None of them would push the sales above 230k on it's own, but together they very much can do it.

Also, while the Switch is still down in the US, it is up worldwide and the gap is growing fast.

Switch will be up the next couple of months in the US too. After May the sales dropped down fast because of lack of supply, which until that point got mitigated with deliveries by airplane.

This isn't a fair way to frame that situation - what you're implying is that the only honest comparison of the systems is the periods where they hit the same price point.

There are other factors at play, for instance, at the stage that PS4 hit that price point it had obviously had more time to accrue a more compelling library of games...

Regardless, the price that a system sells for is a choice made by the manufacturer, which has obviously been influenced by a number of factors, including the spec.

So if Sony chose to go for a more powerful platform in exchange for a higher launch price then they should be held to account for that choice, for better or worse. Nobody is arguing that because some of PS4s extra sales were due to it's higher horse-power in comparison to Xbox & Switch that this should somehow be kept in mind and to an extent held against it when analysing hardware sales. Price & hardware are part of the same equation, as well as other factors, so Sony, or the other two shouldn't be excused as a result of being better placed within these categories or any other.

I could just as easily explain away Switch's recent unremarkable sales due to a lack of high-profile games. Undoubtedly, that has played a role but that doesn't mean that Nintendo gets a pass - the relative drought is their fault. Going by your logic, we can only compare hardware sales in periods where systems have an equal strength of software releases, which is obviously nonsense.

If next gen Microsoft sells XB2 at half the price of the PS5, it is still absolutely fair play to compare the HW sales, as price-point is a fundamental part of the product's strategy that these companies have to get right, which is reflected in their sales.

Finally, you are also comparing a relatively low-powered hybrid to a hi-powered home console - they are very different products with very different value propositions, so contending that they need to be similarly priced in order to fairly evaluate their success is folly in my opinion.

Ok, weird quote here:

“Sony’s PlayStation 4, Microsoft’s Xbox One and Nintendo Switch all achieved all-time unit sales highs for a May month,” said Piscatella. “Previous highs were May 2016 for PlayStation 4, May 2015 for Xbox One, and May 2017 for Switch.”

This is from the official NPD report. Now the "official" NPD leak number for May 2017 was ~195k oor just under 200k. So is this indicating the Switch leak numbers this May are THAT far off?

No May 2017 was 165k

Ok, what on earth is going on?  I distinctpy remember that May had PS4 just over 200k and switch just under at 195k.  https://www.neogaf.com/threads/june-2017-npd-u-s-hardware-predictions-closes-tuesday-july-11th.1400194/ 

https://forum.beyond3d.com/threads/npd-may-2017-sales-results.60221/

That was the number posted to the NPD predictions thread.  Did something happen?  Were these numbers corrected after I left that thread?  And why can't I FIND any of the old NPD threads on this forum to confirm?

These are legit questions by the way as this situation has left me quite confused.

may results were not made public, if you look at the neogaf predtion thread with numbers, insiders were reporting ps4 won npd on twitter even though best prediction had switch winning. magicpork got the right numbers, he has NPD access.
