I think nextgenwars is the biggest lies and pretty much fanboys run website. As we know, VGCharts.org used NPD data in NA and MediaCreate of japan. Where did nextgenwars get their source.. out of no where, didn't site their source at all. It really didn't make sense with their PS3 data. According to Media Create, 490k PS3 sold in Japan. According to NPD Nov, 200k PS3 sold in US. Add them up you get 690k. What do they have now, 820k, so PS3 just sold 130k december in US?. I think not. Also if a website claimed they can track units down to a single digit accurary. That's pretty much lies. Even NPD can't do that.
