Sony's streaming service for classic PlayStation titles, PlayStation Now, will go into open beta beginning on July 31 on the PlayStation 4, Sony announced today during its E3 press conference. The service, which has been in closed beta for several months, allows users to stream content directly to their systems without downloading anything.

The open beta for PlayStation Now will have an array of pricing models for its rentals when it launches. Details for these models have yet to be revealed.

An open beta for PS3 and Vita will launch on a later date.

In addition to this, Sony announced that the PS Now beta will be able to stream 100 games. Dead Space 3, God of War: Ascension, Metal Gear Solid V: Ground Zeroes, and others are playable on the E3 show floor and will be coming to the beta soon.

Sony announced that PS Now will also be coming to certain Sony TVs, with games playable as long as the user has a Dualshock 3 controller.
