PlayStation 4 has been massively successful for Sony this generation, and the popular console is quickly approaching a major milestone. Critically acclaimed exclusives like God of War and Spider-Man helped drive hardware sales in its fifth year on the market. Thanks to another solid holiday season, PlayStation 4 is now sitting at 94 million units sold.
Sony sold 8.1 million units during their third quarter (October 1st - December 31st), which is lower than last year's numbers and lower than Nintendo's Switch sales for the same quarter, but it's still an incredibly impressive figure for a console's sixth holiday season. Sony expects to sell 17.5 million PlayStation 4 consoles for the fiscal year, which ends on March 31st.
At this point, PlayStation 4 only trails the original PlayStation by about 8 million sales, so it will almost certainly reach the mark over the course of the next year. If Sony wants it to catch up to PlayStation 2, they're still quite an uphill battle to be fought there, as PlayStation 4 would need to sell over 60 million more units late in its life.
