Are sale sites lying about WII sales?

This is absolutely not a "anti VGcharts" or "anti WII" (take a close look at my username ey) thread, but these comments I'm very much confused about.

US Nintendo sales not reaching potential

Nintendo's Japanese headquarters shed a little more light on why part of Nintendo of America will be moving from Seattle.

June 22, 2007 - Nintendo spokesman Ken Toyoda has confirmed to Bloomberg that 80 of the company's North American marketing and public relations employees will be relocated to New York and Jose by the end of September, bringing the company closer to major sales and research markets.

One third of employees will be make the move to New York, and the rest will be stationed in San Jose, said Toyoda. He added that sales in the US have not reached their potential, because in the past, Nintendo's sold about twice as many consoles in North America than in Japan or Europe. He also said about 2.37 million Wii consoles have been sold in the US, 2 million in Japan and 1.47 million in other regions, including Europe.

I'm just wondering, if you sum the figures up you won't make it till 6 million worldwide, then somebody can tell me why sale sites like VGcharts for example states a sale figure over 8 million worldwide, while this man claims the WII has sold much less, especially in the US? It's a difference of 1 million in the US only and over 2 million worldwide! Or is this guy just making up some lame excuse to sell even more?
