Just an observation: Many different gopro gimbal stabilizers have been floated but hardly any ever shipped in commercial quantities. Could it be these manufacturers know about an impending design change in Hero 4 which will render their Hero3/3+ stabilizers obsolete?
Haha. It would be amazing if they could do it. I guess gimbals for the gopro can be super compact as the camera itself weighs less than 200g and it's fixed lens, so they don't need to account for varying weights when user mounts heavier lenses, etc. Once you get into DSLM/MILC territory, needs to be designed to support up to 1kg+ at least..
