Some people really need to relax a bit. As long as ioi is aware of the situation it will get solved soon enough; updated numbers are constantly released through other sources. No need for all the melodrama going on here.

And regarding Sony lying about this, I refuse to believe that a company would tell such a straight up lie on stage, they would just stay ambiguous like MS did with Tomb Raider ("exclusively in 2015"), Sony could have just stated shipped numbers for example. But to even say "just to be clear, this is sold to customers" is something they wouldn't do if it wasn't true.

i don't understand, if ioi way is so accurate, why this was undertracked per 60k in germany only and almost all years on US but this month ?

I agree with ioi, and if anyone takes this site seriously they should also. VGC need to find where to plug the hole so they can not only adjust the official numbers but so they can also adjust how they calculate sales for that part of the world.

Makes no sense for them to adjust the numbers while at the same time not adjust their formula for whichever region they are coming up short simply because they don't know where they are coming up short. They would just end up being off every week if they took such a blind approach.

1) I disagree. It makes far more sense as any marketing research company/resource needs to make sure its numbers are credible in order for them to be taken seriously. Better to adjust to the official numbers than to stubbornly stick to less accurate in-house extrapolated numbers.

2) But they're ALREADY OFF every week if offiicial numbers are to be based on. And in this regard by a statistically relevant amount. It's better to adjust into the official numbers, that way you'd at least be right for the week the number is announced and then extrapolate going in further using official numbers as the basis in order to reduce the size of the error going forward.

Marketing guys Sony Marketing again

How many PS4 consoles do you think SCEE sold in Scandinavia?

And why don't you add numbers for all these countries if you have  "very accurate" numbers.

You know, I have to say that I'm a little embarrassed by some users in this thread. VGC has never claimed to be 100% accurate, ioi has stated on multiple occasions that his methods are based on extrapolation and identifying trends, and now he comes into this thread to try and reason and be transparent (something he didn't need to do, but he's making us aware that he knows the problem and is working towards fixing it), with reasoning which makes sense, and all you guys can do are attack him for that? That's a little shameful. If you can't appreciate the way the site works or the site owner, in my opinion perhaps you need to find a new site to visit.

This is the way VGC has always done it. We know it isn't 100% accurate, but it gives us a vague idea. Also, for the regions which people actually seem to care about (Japan, US and Europe), we know that two of those three are almost perfect, so where's the issue here? I just appreciate getting the numbers, knowing they aren't completely accurate, rather than getting nothing at all. Maybe that's just me.

well said.

on a side note. AUS ebay.com.au has had a 20% off sale mid/late last month.  This probably resulted in about 10K PS4 sold.

There is another sale for dick smith  ebay store aus. Same deal PS4 @ $399 AUD with a coucher code.  ATM since the sale started about 4000 units sold:

I know it is not much, but I am sure there are sales like that around the world in smaller regions like this, which would not fit a formula and it is easy to see why the ESTIMATES on this site can be out.
