Renting a PS3 game from PlayStation Now could cost $5 - Is that the sweet spot?

One of the most pressing unanswered questions about Sony's upcoming cloud-powered streaming service PlayStation Now is how much it will cost to rent games. We may now know, as an image posted on the Gaikai website shows a rental for Naughty Dog's Uncharted 3: Drake's Deception will be $5, while you can rent Ubisoft's Far Cry 3 for $6.

The image was spotted by VG247 and remains available through the history section of Gaikai's website. Sony purchased Gaikai in 2012 for $380 million and announced during CES this year that it would use the company's technology to power PlayStation Now, which is now in beta.

The duration of a game rental is not specified in the image. In addition to individual game rentals, Sony will offer a Netflix-style subscription package, though the image today does not mention subscription plans. Sony has yet to officially announce pricing information for PlayStation Now and the company has not commented on today's report.

It is possible that the image posted on Gaikai's website is nothing more than a mockup of what the PlayStation Now user interface could look like.

PlayStation Now will go live in North America this summer for the PlayStation 4 and PlayStation 3. Support for the PlayStation Vita, as well as Bravia TVs and smartphones and tablets, will come later.
