They cited Media Create, GFK, NPD, etc., so I'm not sure that's the case. Unless this new tracking the article talks about involves working more closely with these tracking firms.

While they in fact use as many sourced info data they can get a hold of, this give Sony and others electronic first direct sales data in sold through product retail "unit sold per /discount" data if there is none or if there was, the fact the retail logs data by direct software sourced data and in almost daily basis is quite a good way to track sold through data.

Now that the electronics companies have direct access to such data really does even allow the companies to know a better than a guess of unit sales sold through hell even returnd faulty unit numbers as well!
