So he took the average of NPD numbers for the US. And used them with VGChartz numbers for the US/Canada (+other countries?, I'm not sure). Not to mention he makes the assumption sales stay constant throughout the year, every year. Granted I'm probably putting too much thought into this, and he just wanted to end up with a big number that sounded interesting. I guess more exposure is good for the site, but it would be nice if it came with more thought out comment.
As an aside, going by NPD numbers for the US it would take the PS3 14.89 years to beat the 360. Using NPD monthly sales (US) and VGchartz total sales (America) it would take 17.73 years.
