As has been mentioned previously, Sony is looking into offering a flat subscription fee model for its upcoming PlayStation Now game streaming service in addition to the a la carte pricing currently seen in the private beta."We're working diligently to bring a subscription option to gamers to compliment our rental offering for PlayStation Now," said Buser. "We believe that offering both of these options would provide gamers the freedom to discover and play games in ways that weren't before possible."Buser couldn't offer concrete details about when such an option might become available, and was careful to note that nothing was set in stone. Pricing for PlayStation Now rentals as they exist now are still in flux, with Buser stating that they'll be looking at feedback from users throughout the beta process. Some games will be offered at a rental price as low as $1.99 - one dollar lower than the current lowest price in the private beta. Buser also mentioned that a "rent-to-buy" solution is also being considered, but that with the service still being in its early days, it's simply too soon to tell.PlayStation Now is already receiving a healthy level of publisher support, with 50 companies committing to make their games available for the service. Buser also let us know that 100 games would be available at the start of open beta, and that new games would be added over time. Be sure to stay tuned to IGN for new game announcements as we learn about them.
