Sony will soon expand the PS Now game streaming library with PS4 games, playable on PS4 and Windows PC with a single subscription.

PlayStation Now lets you stream hundreds of PS3 games to your PS4 and Windows PC.

Today Sony said that PS Now's catalog is set to grow even further, as the company will be expanding to include a new platform: PlayStation 4 games. All of the games in the service, including PS4 games, will be included with a single PS Now subscription.

In the next few weeks Sony will kick off a private test with PS4 games on PS Now. If you're an active PS Now subscriber, keep an eye on your email in case you get an invitation.

If you're new to PS Now, the subscription service offers access to a library of games. Since PS Now utilizes our cloud streaming technology, you can access the entire catalog of games, select one, and start playing quickly without needing to wait for downloads.

Also, PS Now uses cloud saves, letting you start a game on PS4 and continue playing on another PS4 or even a Windows PC (or vice versa).
