Analytics firm Nielson has produced a new report that suggests that one-third of PlayStation 4 owners switched from the original Wii console and the Xbox 360. The survey was conducted by 1,200 active gamers from North America aged 7 to 54. The flaw in the survey was that participants were asked which console they currently owned at the time of the survey, not what they had owned in the past. This means that those who sold their PlayStation 3 or Wii would have been listed as non console owners. We already heard earlier this week that Sony were surprised at the success of the PlayStation 4 and were undecided why it’s been such a run away success.
