Agreed. Some users have been waiting for info on this though and they've updated the info today.
They are saying 2-3 weeks out for pre-orders now but that might change and they have a no refund policy.
It's a "Premium" solution in any case.
If you destroyed your Vision+ gimbal and want to replace it with a GoPro, It will cost you $298 Euros ($378 USD) + another $379 for the Zenmuse gimbal + the cost of the GoPro if you don't already have one.
Compared to the $600 to just replace the Vision+ camera.
It relays the video feed from the GoPro to the Vision app, but there's no remote control of the camera in the air.
