Over half of PS4 owners are also PS Plus subscribers

Sony is "very excited" with the growth of PlayStation Plus. Following reports that PS Plus subscriptions have grown 90 percent since the PlayStation 4's launch in November, Sony revealed during its recent earnings call that over half of the 4.2 million (as of Dec. 28) PS4 owners are also PS Plus members.

"I'm going to just add a little more color by saying that 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," said Sony Chief Executive Officer Kazuo Hirai. Let's also remember that this doesn't take into account PS Plus members who only own a PS3 or Vita.

Much of the boost in subscriptions could be due to the fact that the PS4 requires PS Plus in order to play games online (online play remains free for PS3); but, it helps that Sony offers incredible value with the subscription. Each month, Sony offers a number of games for free across its platforms: PS4, PS3, and Vita. February's offerings saw Outlast for free on PS4, Metro: Last Light, PayDay 2 and Remember Me on PS3. Oh yea, that's also not including the numerous discounts offered to PS Plus owners. So as you can see, the subscription is clearly worth it.

And it's clearly worth it for Sony as well. Though figures weren't announced, Sony Chief Financial Officer Masaru Kato said that the additional revenue stream brought in by PS Plus subscriptions is "very promising for us."

"And I think that is what the success of the PS4 is for us going forward," Kato added. "Sorry, I cannot give you numbers, but we are very excited."

For you PS4 owners out there, do you currently subscribe to PlayStation Plus?
