That was the estimate heading into the show and now it's official.
During their Gamescom briefing today, Sony confirmed that PlayStation 4 had reached 10 million sold worldwide. Sony boss Jim Ryan reminded everyone that this number is a sold-through statistic; in other words, it's not the number of console shipped, but the number of systems actually sold to consumers.
The company said this represents the "fastest and strongest growth" in the brand's history. Said Sony in a statement:
"The responses we have received for the PS4 system's unique gameplay experiences powered by the network, along with its vast game portfolio has been phenomenal, and I am absolutely delighted that PS4 was able to reach this commemorative milestone in less than 9 months. We're so grateful for the enormous support from PlayStation gamers worldwide, and we look forward to bringing even more exciting content and services in the months ahead."
As for software, Sony has moved a combined 30 million copies (total retail and digital) as of August 10. Yes, this generation has proven awfully successful for PlayStation.
