The last home system to hit the 100 million mark was the Wii.
Video game industry research center DFC Intelligence anticipates that the PlayStation 4 and Xbox One will both sell 100 million units by 2020.
The report, which DFC Intelligence shared with GamesIndustry International, also projects video game revenue over the next few years; the center raised its worldwide game revenue forecast to $77 billion this year, up from $68 billion in 2013. It also states that video game revenue could be in the neighborhood of $100 billion by the end of this decade, thanks to the “core gamer spending more than ever.”
DFC said that “price and strength in Europe give the PlayStation 4 a slight edge;” a difference that might also factor into the PlayStation 4 becoming the biggest console launch in history, though the Xbox One led console sales in December 2013.
The PlayStation 4 and Xbox One were released one week apart in November. The Nintendo Wii was the only system from the previous generation to hit the 100 million mark.
