Most of us expected it, but the PS5 has been given a launch window of Holiday 2020, and the new controller has a couple of new upgrades.
The first is the haptic tech used to replace HD rumble. This will apparently give a lot more variety to how the controller vibrates in your hand giving more power for developers to craft your experience.
The second is the use of adaptive triggers which will give developers more power to determine how the triggers are used with regards to sensitivity.
