Though Sony has announced that the streaming game service will come to tablets and smartphones — perhaps even non-Sony devices — the company doesnt plan to let you use a touchscreen. To play PS3 games, PlayStation marketing VP John Koller tells us, you need to have the gamepad they were originally designed for. You need to have the DualShock to be able to play, says Koller. Sony tells us a DualShock 4 will do for the PlayStation 4, and the PlayStation Vita handheld buttons can continue to work the same way they do now.
