PS4′s DualShock 4 pad works with PS3
It looks like you’ll be able to plug your PS4′s Dualshock 4 controller into a PS3 and play certain games with it. German games site Computer Spiele successfully tested the PS4 pad with PSN title Urban Trial Freestyle, though they reported problems attempting to use the pad wirelessly.
PS4 pad compatible with PS3 games
In the video below, a friendly Computer Spiele presenter hooks up the DualShock 4 to a PS3 via the controller’s sync cable, and successfully controls Urban Trial HD with it. Obviously the central touch pad’s out of action, but the sticks, triggers and buttons all report just fine.
Sony’s also confirmed that the DualShock 4 will be PC-compatible (again, apart from the touchpad), so there’s a fair amount of use to be had from it. The real question is: does PS4 support the DualShock3? In sort, no. Shuhei Yoshida confirmed that the next-gen console won’t recognise current-gen controllers earlier this year.
