Just found some info on how this Amazon ranking works http://www.amazon.com/gp/movers-and-shakers/videogames#learnmore "The Movers & Shakers index identifies, by category, the biggest gainers in sales rank at Amazon.com in the past 24 hours. For example, suppose a music item has a sales rank of 10 today, but was ranked as low as 30 yesterday. Its Movers & Shakers increase would be 200 percent."
Meaning that since the PS3 was #33 24 hours ago, and is now #1, it had a 3200% increase. It has nothing to do with actual sales, but position on their ranking. So the PS3 has not had a "2800% increase in sales" as the article title states. It has had a 2800% increase in ranking.
