More than half of the 4.2 million PS4 owners have taken out a PlayStation Plus subscription, Sony Corporation CEO and president Kaz Hirai revealed during last week's earnings call.

"Of all the 4.2 million PS4s that have already moved into the hands of consumers, more than half of the people that have now gotten their hands with the PS4 have actually signed up for PS Plus service, which bodes very well for us as well," explained Hirai.

"And we'll obviously be sharing more details as the months go on."

Sony also noted that there are now over 150 million PSN members, with the number growing thanks to the launch of PS4.
