Has anyone tried to use the Mavic 3 with GSP? I don't see a "built-in" camera for the 3 yet BUT you could set up a custom camera.

Hello there mikes1. Good day and thank you for reaching out. As of this time the DJI GS Pro ( https://www.dji.com/ground-station-pro ) is compatible with the following DJI aerial platforms and flight controllers: DJI Mavic 2 Enterprise, DJI Mavic 2 Enterprise Dual, DJI Mavic 2 Pro, DJI Mavic 2 Zoom, DJI Mavic Pro, DJI Phantom 3 Standard/4K/Advanced/Professional, Phantom 4/RTK/Pro/Advanced/V2, P4 Multispectral, DJI Inspire 1/Inspire 2, Matrice 100, Matrice 200 V2, Matrice 210 V2, Matrice 210 RTK V2, Matrice 200/210/210 RTK, Matrice 600/600 Pro, A3, N3. Thank you.

Seems very unlikely since DJI is saying there will be no waypoint capability for the M3.

Yep, I haven't researched it yet but I'll bet IOS will not be supported and GSP only runs on IOS. That alone will cause me to pass up this drone.
