Drone expert are taking pre orders for the quick realese system which will enable people to fit a go pro with gimbal on a vision + .Looks like a good set up  and if you are unlucky and smash up your v2+ camera/gimbal then you can replace it a go pro system.
I opted for the v2+ and i already had a gopro but the v2+ just seemed to suit my needs but now its nice to know that i can replace the system at half the cost ! only because i already own a go pro.

Agree totally, I have several Gopro 3+Blacks great for night time. DJI needs to copy the setup.

Interesting in QRelease system as you said. Can you show me the link please?

Try the Quickrelease from Dronexpert.nl

You can use your GOPRO_H3 or H4 on your Vision_plus platform, together with your Vison APP.

this is a need for many of us at the moment

So, if you buy that and connect the GoPro 4, do you still have the gimbal for smooth gopro video, or does the gimbal come off with the P2+ camera?

The gimbal comes off and you use the zemuse setup for the Gopro.
