It’s official people ( well as official as me telling you for now 🙂 ) that there will be a DJI Phantom 4 Professional. NOTHING is really known about this as yet in terms of specification but what info I have came from a leaked “DJI GO PAD” app that was embedded into an Android OS ( rumored built in screen RC for the Mavic ). Anyway, withing that app there is numerous mentions of a Phantom 4 Professional, not least it mentioned in the dropdown of models ( image above )
The App itself works with the current Phantom 4 but detects it as a Phantom 4 Pro ( and 3 later in the App ). The functions of the all seemed the same although the interface has changes to be more suited to an RC with a screen.
