PlayStation Now all-you-can-play subscriptions hit next week for $20 a month, $45 for three months

Sony plans to launch PlayStation Now, its PS3 game streaming service, for the PlayStation 4 on Jan. 13 in the U.S. and Canada for $19.99 a month or $44.99 for three months, the company announced this morning.

The service will hit the PlayStation 4 first, followed by other PlayStation Now enabled devices, according to the press release.

A seven day free trial will also be available at launch. The subscription offers unlimited access to more than 100 PlayStation 3 games from publishers like Sony Computer Entertainment, Sega, Warner Bros. Interactive Entertainment and Bandai Namco.

"Users have been able to rent games through PlayStation Now for several months, and one of the top requests we get is for an overall subscription to the service. We're excited to formally announce it today, as the PlayStation Now subscription service will deliver a ton of value by providing instant access to a large and diverse catalogue of games for one low price," said Phil Rosenberg, Senior Vice President, Business Development and Publisher Relations, SCEA. "We know there are lots of PS4 owners that never owned a PS3, and this is a great way to catch up on games they may have missed."

The service allows gamers to stream PS3 titles without the need to download, install or patch the game. Game sessions can be saved on PlayStation Now's cloud servers. As the service expands to other devices, users will be able to access supported games across any supported device with a single subscription.

The service will continue to support a variety of rental periods, according to the updated website.

All the games available for play at launch are shown in the image above, a PlayStation spokesperson told Polygon.

To celebrate today's news, Sony created a free PlayStation Now theme for the PS4. If you download the theme before the end of the month, you'll be entered into a drawing for a chance to win a one-year subscription to PlayStation Now.
