While PlayStation Now may be being pulled from devices like the PS Vita and PlayStation 3, Sony is doubling down on the PlayStation 4 and PC support. In addition to the current collection of 480 PS3 games, players will soon be able to access PS4 titles on PS Now. While no games are confirmed, it's unlikely any extremely recent PS4 titles will make their way to the service. Regardless, because of how PS Now streams the game to your PS4 or PC, this will become the first way to legally play a PS4 game on PC without owning a PS4.
There is no word on whether the current $20 a month price will change and no solid release date for PS4 titles to come to the service. But overall this seems like a positive direction for PlayStation, bringing more of their games to a wider audience.
