I think what you're doing is confusing your experience with scientific research with consumer research. In the scientific field, people are given money/grants to actually conduct the research, but their findings are always made public. In consumer research, these researchers only get money from companies who are willing to pay for their results. So, it wouldn't be very lucrative for them if they published exact details about their research publicly, as no company would need to pay for the results.
Plus, these companies only get popular, and therefore hired by more businesses, if their research is proven to be as close as possible. So I wouldn't be too skeptical about them not being upfront with their info with Average Joe's like us. And according to the OP's source, this info actually comes from Playstation: The Official Magazine. So, I'm guessing either the mag is a client or Sony is and just passed the info along. But either way, they probably didn't have permission to go into specifics other than the info about the weekly 1,000 gamers asked.

Kind of a small correction, but they are actually 20th in the US. 24th WW, though.
