Sony's latest patent filing reveals a new PlayStation controller is in the pipeline.

The design will not surprise anyone who's familiar with PlayStation controllers. It aligns closely with the existing DualShock 4 model, offering an identical layout for the action buttons, directional pad, and analog sticks. However, Sony did sneak in two more buttons. They're apparently programmable buttons that can replicate what others on the controller do.

Polygon warns that this controller might not belong to Sony's next-generation video game console. In the patent, the Japanese company inserted a micro-USB port. The PlayStation 5, however, has been rumored to use a USB-C port on its controller. With that said, perhaps Sony is developing this controller for the PlayStation 4.

A few years ago, Microsoft introduced a pro-style controller with customization at the forefront. It now sells the Xbox Elite Wireless Controller Series 2 for serious gamers, and third-party companies such as SCUF design similar controllers. It'd be wise for Sony to follow and offer a similar first-party controller as soon as possible.

Sony did announce an attachment for the DualShock 4 model featuring programmable buttons, and the patent might represent a version of the controller with them built-in.

The PlayStation 5's controller will support haptic feedback. Gone are Sony's classic rumble motors, and now gamers will notice localized feedback. In addition, the controller will have adaptive triggers. Developers can program the resistance of the L2 and R2 triggers on a per-game basis. Combined, these capabilities should result in more immersive games on Sony's platform.

We're still waiting on official details, but Sony did confirm it'll release the PlayStation 5 in late 2020. Mark Cerny, the architect behind the PlayStation 4, will lead development. When it does arrive, the gaming industry is in for an all-out war between Sony and Microsoft as the Xbox Series X will debut around the same time as the PlayStation 5.
