Guys I made a mistake. The panels they have on the floor are the older panels. The new hardware is not ready yet. But I can confirm its USB based, no track pad with mouse buttons (4th track ball and wheel acts as that or you can use another mouse) I just finished teaching for the day at Post Production world will post pics before AJA party tonight
The panels on the show stand are using the original metal work, but have updated electronics. The redesigned panel metal work will be very similar to what you see on the stand, with the exception that the trackpad will be removed. The panels are USB connected to the Resolve system.
