Newsbrief: Sony claims that nearly a third of people who own a PlayStation 4 did not own a PS3, but rather, came from owning an Xbox 360 or a Nintendo Wii. PlayStation VP of marketing John Koller told Kotaku that, according to a research study carried out recently, 31 percent of PS4 owners are new to the PlayStation brand. And he claims that 17 percent of people who own a PlayStation 4 did not own a console last generation. In other words, nearly half of all PS4 owners did not own a PlayStation 3.
