Sony is taking its closed beta for PlayStation Now and making it an open one. At least for PlayStation 4s in the United States and Canada, on July 31.
"Shortly after," the open beta will extend to PS3 and Vita, as well as "select Sony TVs." You might be able to play games without buying a Sony console if you have one of their overpriced TVs. Sony name dropped Dead Space 3, MGS: Ground Zeroes, Ultra Street Fighter IV, God of War: Ascension, and Ratchet and Clank: Into the Nexus as PS Now playable games.
