Plenty of folks were not aware that DJI had closed the line, but starting today you can pre-order the Phantom 4 Pro again.
The re-release timed to coincide with CES.
This will no doubt be fairly short-lived as the next larger than 250g DJI drone is going to have to comply with Remote ID (RID) from EASA and the FAA.
This video explains it very well.
In 18 months time, your buying decisions will be informed by potential compliance.
Just keep that in the back of your mind.
