This seems like a very smart move for GoPro, in that they can sell you not only a camera, but the drone that will carry it.
Instead of simply making the cameras and letting other companies like DJI base their entire drone platforms off of it, GoPro can simply make their own drone, as well as continue providing a camera for other manufactures to use. Maybe this is why DJI has only shown their new Inspire 1 drone with their proprietary camera, even though its very similar in size to a GoPro?
The drone world is just beginning to explode, and getting in early as the "affordable and accessible" camera & drone manufacturer can only help them long term by diversifying their product line and pioneering the "next big thing" in video.
