It's a shipped number, i can't believe these threads still come up every time financial reports come out with people claiming they are sold to customers, even posters that have been here for a long time. I will agree with people in here who are saying that it's hard to believe there are that many PS3s on shelves. To the contrary there have been shortages. I find it really hard to believe there are more than 2 million on shelves, even that may be pushing it.

However no documented shortages by Sony or any game news Ive seen. So obviously it was just normal here and there out of stocks. Like the 360 would have also had.
