No point discussing stuff with this aeolus guy.

If he's never heard of GfK before then no wonder he's defending VGChartz numbers so much.

At least in his last post he has the sense to admit that Brett guesses his numbers on here and then adjusts them when the big 3, NPD, GfK & others release their numbers publicly/through leaks and correct him.

As I said before, some of the numbers on this site are accurate thanks to publicly available / leaked data. A lot of the numbers of this site are just wrong, hilariously so. 

I know this because I've been following the industry for a very long time and becuase my current employer has relationships with some of these organisations meaning I have access to various research reports. 

IDG are the trusted forecast vendor for a number of organisations within the video game industry. 

They fully track and forecast console hardware sales to end users on a global basis, as well as this they have a consulting service, insights service and research service that focuses around the whole video game industry including digital. They release reports every 3 months and recently released their 2015 report where they forecast a total of 34 million PlayStation 4's and 20 million Xbox One's will be sold through to end users by December 31st 2015. (Numbers have been rounded)

I believe they have over 30 years experience in doing this and they use a wide variety of sources including internal research, NPD, GfK, partner reports, financial reports and general industry contacts in order to ensure that their services that they provide to clients are as accurate as possible. 

Clients that subscribe to IDG include but are not limited to Nintendo, Microsoft, Sony, Square Enix, Nvidia, Sega, Ubisoft, Tencent, Facebook, Activision, Atari, Best Buy, Capcom, Konami, JPMorgan, Barclays, GameStop, Namco Bandai, Time Warner, Warner Brothers, Codemasters, Deutsche Bank, GAME UK, Morgan Stanley, Rockstar, Take Two, Viacom & Disney.

Hi Shu thanks for Last Guardian don' stop smiling at Press conferences.

I'm not defending the accuracy of vgchartz numbers. The majority of the regular forum goers understands the numbers here are estimates of worldwide video game sales and that gives us plenty to converse/debate about but I'm against your constant knocking of the site and it's estimates. You're adding nothing of value to discussion by doing that. 

I think we should all step back a bit and take it easy. Some people just never heard of IDG or GfK Chart-Track. However, let's not condescend them, but rather teach them. Don't get me wrong. I'm as skeptical as you are when it comes to VGC's numbers.

Hmmm, I wouldn't so casually compare VGChartz and IDG. There is a reason IDG are most trusted in the industry and why VGChartz are not.

For one, IDG uses definitive values for each region as provided by NPD, GfK and Enterbrain in order to fully estimate total sell through. They of course continually use this data to update their tracking and provide a very accurate picture of the current install bases at all times. Of course in regards to the forecast service they provide that is based on estimatations and trends etc.... But their current tracking is very very accurate and you'll see IDG figures quoted by leading organisations, the latest of which I believe was Take Two during their recent earnings report. 

VGChartz does not have access to real time sales data provided by NPD, GfK or others and therefore he estimates based on shipment reports and polling. He corrects his data when one of the above sources release a public number or have a leak. That is very very different to how an actual market research organisation operates. 

Hes downplaying it because he doesnt like how VGchartz is exposing accurate numbers to everybody without his permission 

VGChartz use Media Create and Famitsu for their Japanese sales data.

Yeah and own sources as well

Sure. Let me bring up his schedule.

He's free at 4 A.M in the morning.
