Hmm, new DJI drone controller and screens appeared briefly in the DJI  newsroom, customisable buttons, 3 screen options and separate lower  inbuilt screen to show flight parameters. Also a new long range tripod  mountable antenna that can track drone with 10km range quoted (not part  of the controller). Might have been a slip up with the new drone stuff as it disappeared  quickly...

It's here and it's not for Phantom users:

They also list prices for Crystalsky monitors.
