We know that Sony Interactive Entertainment is working on the new PS4 Neo, but apparently PlayStation's engineering team has something else in store: today the Federal Communications Commission published the first documents related to a new model of the DualShock 4 controller, with the product code "CUH-ZCT2U."

You can see the label below, and the spec sheet at the bottom of the post.

The new controller has the same weight, the same power supply voltage and battery amperage as the previous three iterations registered by the FCC. The only visible difference in the specs is the Bluetooth antenna. That said, there is one difference in the code that stands out.

All DualShock 4 models since the release of the PS4 used the CUH-ZCT1 code, excluding special editions like the Star Wars one, that have a completely different code. This is the first model that makes a digit jump from the original, moving from "ZCT1" to "ZCT2," possibly indicating the first major revision of the controller.

At the moment, the analysis of the documentation didn't turn up further information, which is understandable, considering that the FCC certifies only a piece of hardware's radio equipment.

We'll keep you posted if anything else comes up.
