Sony has been rather successful in selling the PlayStation 4, to the point where the PlayStation Network has strained under the load. The company doesnt want to worsen these problems with its PS4 launches in Australia, Europe and New Zealand, so its taking an unusual step: for the first few days after release in these areas, its disabling friend activity in both the Whats New and content info sections. Activity will come back once the initial frenzy is over, Sony says.
