Logic? You say, well ioi, just stated in front of everyone in this thread, that he does not accept  data from the companies themselves unless an indipendant 3rd party can confirm the data, well as I just pointed out before Sony went on stage insider derp already listed the sales of the PS4 over 10 million sold through, does that count or only certain 3rd party tracking services only?

What if the people here demand ioi data to be confirmed by another source outside VGchartz, you know to make it fair and above board. You see how funny that Sounds, on one of the freaking largest game conventions infront of freaking millions, an there was a press release to boot, but yet ..what do we hear, we need another source to confirm this..

Playstation Blog posted by SHAWN LAYDEN

We just announced that the PlayStation 4 has sold through more than 10 million units worldwide –- and more than 30 million PS4 games have been sold –- since its launch less than nine months ago. It’s a remarkable milestone that reinforces PS4’s record-breaking pace and the movement it has created among players globally in defining next generation gaming.

On behalf of our entire team, I want to thank you for your support and passion. You’re the reason that PS4 is the #1 next generation console in the world and we’re grateful for your continued enthusiasm and for always pushing us to new heights.

Rest assured that the PS4 journey has just begun, and we’ll continue the momentum this holiday season with blockbuster titles, including Destiny, DRIVECLUB, Grand Theft Auto V, inFAMOUS First Light, Little Big Planet 3, and NBA 2K15, and innovative titles including Grim Fandango, Hotline Miami 2: Wrong Number and Minecraft.

In addition to our expanding gaming library, we’ll also continue to enhance the PS4 system’s network features to offer more breakthrough gaming experiences. Upcoming features include the ability to upload game footage directly to YouTube, and also “Share Play,” a new feature that allows players to invite a friend to a game—even when they don’t own a copy of it.

I look forward to sharing more details about new games and features coming to PS4 that clearly demonstrate why PlayStation is the best place to play.

Do they need to hand-deliver? I don't understand.

He didn't say Sony was lying, he says they can't follow the statement blindly because the numbers must match with other sources.

The same rules apply to any company. Imagine the following scenario: the amount of sales creates perception about the product. People believe that the bestseller is obviously the better product. So Sony or Microsoft could easily say that they sold 30 million. It's a very positive number.

They don't need to specify their reports since they are secret.

They don't need to explain anything.

But this site does.

Don't worry, Sony is not lying, but so long VGChartz need multiple sources to specify which regions are buying and other details, they can't take Sony as the only source. Where is the system selling? Japan? Nobody knows. So they add sales to that graphic and what happens to the others sales projection? They break.

It's a matter of security and trustworthy as much as a college works can't use a single specialist as source, it would be considered a biased work and your teachers won't give an A+ for it.

Add an extra column "Magic Console Dust", 600,000 units.

Since they are a pro client will they eventually tell you where that 600k came from? I assume you've already asked them.

Well and being Sony a customer of Pro (they probably subscribe to all trackers with decent enough methodology and credentials) they are probably quite aware of the inaccuracies on their numbers and accept that as what the site promises trends and ballpark, and mainly a good idea of competitors.

Anyway I think you already saw that at least in this thread most are being polite and accept that there are a margin of error in the estimative and their problem is either on how you worded the "if sony is to be trusted" not that matter, you have the right to be confident in your numbers... and the sensible users accept that first you need to find were the deviations are to correct them.

But Sony claim of over 10M sold through in 10th of August aligned with 10M+- shipped on June 30th is pretty solid for me.

"if Sony's number are to be trusted"

sounds more to me like he insinuating that Sony may be untrue in their sales projections (may not be so though). The problem is that VGChartz is almost never right about their own trackings. ioi himself told me he uses the number of new XBL and PSN accounts to estimate his trackings. 

with this method, what about countries in Tier 2 areas like eastern europe or South Africa or India where the internet might be terrible or non-existent but the PS4 is still selling quite well? The problem is that it really seems like the tracking system on this site is lacking severely.  However, It gives out estimates and most certainly the leading console on VGChartz is always the leading console (even when the gaps arent always correct) when the official data is released so people still stick to this site

Also the community isnt too shabby either. 

Sure sony estimate have errors, but since they didn't gave a exact number like 10.2M... just a over 10M i'm pretty sure their margin of error is small enough for us to accept 10M as good enough, or would you say your 600k under is closer to the "exact number" than Sony because of the sum of the 3rd parties tracker with your estimative of RofTW?

well, I apologize for that. might have unduly accused you of something you didnt intend but I need to ask a question.

How do you track the other 60+ regions not listed on the homepage of this site where the PS4 is currently selling?
