The VGChartz Network is a network of five video game websites - VGChartz, gamrFeed, gamrReview, gamrTV and gamrConnect.VGChartz itself sits at the centre of the VGChartz Network and is a video game sales tracking website that provides weekly sales figures ofconsole software and hardware by region. The site was launched in June 2005 and is owned by Brett Walton.[1][2] Employing ten people,[3]VGChartz provides tools for worldwide data analysis and regular worldwide written analysis of the data it provides.
VGChartz provides tools for data analysis and charting and regular written analysis of the data referencing major news in the video gaming industry. Sales figures on VGChartz are based on estimates extrapolated from small retail samples.[4] While offering some information about their methodology through their website,[5] VGChartz does not publish any sources on how they get their data. Some sites, includingGamasutra and Wired News, have questioned the reliability of the information presented by the site.[4][6] VGChartz has defended the credibility and reliability of its sales data,[7] often comparing their numbers with the ones published by NPD Group,[8] although some charts have been retroactively adjusted to better match NPD's monthly reports.

today's era of gaming, the console war has driven industry interest in sales to an all time high. Every month many gamers are sitting on the edge of their seats in anticipation of the release of the NPD Group's numbers. In the meantime, they check sites like VGChartz.com to track the sales figures of each console and game and see how they are doing.
Since its inception in September 2005, VGChartz has not been considered a reliable source of data by many companies and websites because they have never disclosed the sources of their information. If the source is unknown, the legitimacy of that source can't be verified and thus the information can't be trusted. One example is Wikipedia, who themselves are known to be somewhat of an unreliable source to reference, refuses to acknowledge VGChartz as a reliable source and any bit of information citing their website as a reference is promptly removed.
Microsoft's latest financial statement may have shown precisely why VGChartz numbers are not trusted. For its fiscal year ending in June, Microsoft announced that they had sold a total of 41.7 million Xbox 360 consoles worldwide since launch. If one were to compare this figure to the chart found on the main page of VGChartz, you would see it is slightly off. Their graph shows only 41.4 million Xbox 360's have been sold worldwide to date. Clearly, Microsoft's number is the one to be trusted.

You posted a nerd's blog post with the same asinine logic as your own.
that is pretty much the same number. I could see if there was really only ~70 or maybe ~75 PS3s sold but the argument over probably less than the margin of error...
