I don't think anything is transferable, maybe just the micro usb cable.
Its a completely new system with the 90's look. They should have given it red motors or something for that premium feel.
I don't even think the battery charger is the same. They will change the pins to stop people from accidently using the wrong batteries/charger.
They still adopted the fragile gimble + cable combo - DJI's parts cash cow!!!
