Just yesterday, it was revealed that Sony will announce a new PS4 Slim in September. The person who got their hands on the console has revealed that the controller is also being redesigned.
They posted a video online, though that video is now private, which showcased the new controller. It features a see-through strip along the top of the touch pad, which allows light from the light bar to shine through.
At the moment, it's unclear whether this is simply an aesthetic touch or if it will have a practical function.
There are going to be plenty of rumours and leaks in the coming weeks ahead of Sony's announcement on September 7, so take them with a pinch of salt.
