The official PlayStation Twitter account confirmed the next-gen console had surpassed the initial sales of the PlayStation 4, although the company has yet to share official sales figures.
Back in 2013, PlayStation's then-CEO Andrew House said the PS4 had sold 2.1 million units in just over two weeks, declaring it "an impressive and record-setting accomplishment for our company and for our industry.".
A few days later, PlayStation quoted analysts at DFC Intelligence, who confirmed the PS4 was the biggest launch in the history of games consoles.
