The worldwide sell-in total for PlayStation 3 has teetered over 50 million units, Sony has announced. PlayStation Move, the platform holder added, has shipped more than 8 million units. The PS3 total was calculated on 29th March; the Move total on 3rd April. Remember that these are sell-in numbers, which means the same thing as shipped: i.e. consoles sold to shops rather than shoppers. source http://www.eurogamer.net/articles/2011-04-15-ps3-worldwide-sales-50-million-shipped
