Update on the ps5 firmware?

We don't have a date yet for the compatibility with the DualSense controller. We do however have compatibility with 3rd party licensed controllers such as the Hori PS4 Mini controller. You can plug in these controllers in place of the PS5 controller on the K2 and it will work without interruption. They are usually about $29 on Amazon, but they are often out of stock since they are the cheapest PS5 compatible controller and a lot of people buy them.
