Actually, no, it's likely because for whatever reason Sony's releases aren't itemized the way Microsoft's releases are.  We've run into this problem in the past where Sony's given clear unequivocal statements regarding sales figures and they've not been updated for weeks on end, whereas, a communication from Microsoft prompts an update w/in 2 days.  The response then, was, due to an itemization difference they didn't know where to add/subtract numbers from certain parts of the world, and rather leave the total sales knowingly incorrect, than giving one part of the world incorrect and the totals accurate.

Well, if it helps, VGC has the US total as of April 2 at 13.5m, when it's really at 13.35m. So ~150k over in US.

2014 LTD on VGC is 6.84m, while it is actually 6.68m, so LTD 2014 in the US is over 160k.

2015 LTD on VGC is 12.53m, while it is actually 12.39m, so LTD 2015 in the US is over 140k.

Germany LTD at the end of 2015 is 2.8m http://www.playstationlifestyle.net/2016/01/21/report-ps4-vs-xbox-one-sales-in-2015-in-france-germany/, and VGC has that at 2.635m. That's actually under by 165k.

In the same link, November + December sales in 2015 were 570k, and VGC has total sales there at 566k.

France is in the same link, however, the numbers in that link are sorta outdated in that the numbers were readjusted. Actual sales at the end of 2015 are 2.18m and VGC is at 2.157m. Under by 23k.

UK and Japan are pretty close, and doesn't need to be looked at. 

Looks like the over estimating is coming from NA and other contires within EMEA.

i don't really care about the regional numbers. We have NPD and outlets in Japan for numbers. the ROW numbers are pretty much up in the air. What I do look at though are shipment numbers 

The old Shipped=sold eventually thing. 

If at the end of March Sony had shipped 40M units. That means Sony makes/ships on average 1.4M consoles every month. Some months more and most months less. 

It also means that as of the end of April that number has probably gone up by another 1.2 to 1.4M unts. Putting the new total shipment at 41.2M or 41.4M. 

Now as of the end of January Sony announced actual sales of  36M or so. That's a sales average of around  (surprisingly) 1.4M/month. Now we all know that most of the sales happen in the last 3 months if the year so the average monthly sales of the PS4 is probably around 800k to 1M on non end of year months. 

In the 4 months of this year it's thus safe to estimate that the PS4 has sold 4M consoles so far. Which pretty much ensures that total sales are currently above 40M  and there are still like 1.2M PS4s in the channels. 

You assume that shipments would stay consistant going into Q2, when it always goes down. Sony shipped the lowest amount of units last quarter they have had for the PS4 yet, with 2.3m, or less than 800k a month. In April, that would either go down or stay flat since they have UC4 in May, so the PS4 is probably less than 41m shipped at the end of April.

Sold through is a bit trickier, but if we assume the PS4 continued to sell around 1/3rd of its total worldwide sales in the US this year, the PS4 has sold around 3 million this year, or 1 million a month, or 39m worldwide by the end of March. April is a slower month in sales than March, so 1 million sales would not happen, so the PS4 should still be below 40 million by the end of April.

So I'd say as of the end of April, the PS4 is <40m sold through, and <41m shipped. Over 40 million at the end of April doesn't make much sense.

It was equally (I'm being very generous) often undertracked. There was a rather famous 1m adjustment upwards you are obviously forgetting. Almost every shipment report showed HUGE supply which meant undertaking.

Actually Q2 is bigger than Q1 for Sony. Just look at their shipped numbers (rembember that Fiscal Q4=calendar Q1, so in this chart, Q1>Q4 => Q2>Q1:

That said, they most probably did not ship 1.4 million in April.

I don't believe those Wii U EU numbers at all.
