Sony announced during their Gamescom press conference that the PlayStation 4 had surpassed the 10 million units sold mark.
“Just in case that wasn’t clear, that’s sold through to consumers,” Ryan said.
“Sold through” means the consoles have left stores and are in the hands of players. For reference, “Sold in” is how many have been sent to the retailers but may be sitting on shelves.
Microsoft hasn’t released sales figures of the Xbox One recently, however it is assumed the numbers are behind that of it’s Sony counterpart.
