But the biggest change can be seen on the back of the controller. The new design adds two back triggers to the controller. Unlike the new accessory that adds back triggers to existing PlayStation controllers, these seem built into the controller itself.
New PlayStation DualShock Patent – Back Triggers
It’s unknown what the patent is for specifically. While there’s a chance this design could be intended for the PlayStation 5, there’s an equal chance that this design is meant for other products like the existing PlayStation consoles. Furthermore, companies regularly request patents for designs that never end up being used.All we know for sure is that Sony is currently working on the designs for the next-gen PlayStation 5.
