Numbers were catalogued from prior threads. I'm pretty sure all the numbers came from Aquamarine and librarian13579.
Sony's numbers were global shipments, not U.S. sales. It's been pretty well established for a long time now that shipments ≠ sales.
According to NPD, the PS4 sold 381k in the U.S. in June, up a good bit from last year. Overall, Q2 sales in the U.S. were up by 158k units, or 25.6%.
In Japan, sales were very slightly down YoY. Media Create had the PS4 at 294,000 for weeks 14-26 last year, but only 292,368 for the same period this year, a dip of only 1632 units, or only 0.56%.
As for Europe and smaller markets outside the NA/Japan/Europe triad, I don't know, but if actual unit sales (as opposed to shipments, which did decline by 5.7%) were down YoY for the April-June period, the loss had to come from outside the U.S. and Japan.
It should be noted that Sony has had a lot of units on shelves as of march 30th, so global sales can definitely be up even though shipments are down.
