I stopped reading at this point:
"As a result, we get to what VGChartz actually is - a strange mixture of a prediction market (as consensus prediction site TheSimExchange is) and a retroactive, but non-credited reflection of charts that have historically been known for having more concrete data."
The previous parts of the article in no way support this assertion. I can only assume that from this point on, the author totally forgets that VGChartz has contact with retailers, which, if nothing else, is obvious when you look at the Japanese preliminary data. Of course, I'm not going to waste my time reading any further... If the author wants to be taken seriously, he can't suddenly start claiming something like that without preparing the reader for that claim (especially when the sentence starts with "as a result").
Software numbers are obviously not accurate enough yet (although they've been getting better). However hardware is quite accurate already, and I don't see a way to achieve that accuracy with "a mixture of a prediction market with number adjusting", since VGChartz's figures are published earlier than NPD's. There were several unpredictable trends shown by VGChartz's data, something which no prediction market would get right by luck more than once or twice.
