Sony claims that nearly a third of current PlayStation 4 owners owned a Wii or an Xbox 360. Around 31 percent of consumers who bought a PlayStation 4 had an Xbox 360 or Wii but not a PS3 in the last hardware generation, PlayStation's American VP of marketing John Koller told Kotaku in an interview conducted at E3.
The data Koller was citing comes from a new research study – the origins of which are not revealed. Koller also said that as nearly 17 percent of people who have bought a PS4 didn't own a console at all in the previous generation.
Koller also noted that the hardest of the hardcore gaming population are the primary people buying the PS4 up until this point.
"The person that we've picked up since launch primarily is someone we call the connoisseur, someone that loves, unequivocally, loves games," Koller said. "They are the people who, when you walk in [to their home], there's no books on their book shelves. They're all game packages. They're the people who stood in line at midnight [for the console's launch]. They really are a fantastic consumer for us. They're a great part of the PlayStation nation."
