I have followed the GoPro development from day one. His early interviews were excellent as he was getting starting. He had an idea, it worked and he got traction. But he payed attention to what his customers were doing and followed them. That's when his business exploded. Some cash to grow and boom, fast expansion. I wouldn't bet against him.
I'm really hoping he comes out with a detachable gopro (or at least very small) camera without fisheye, f-stop control for exposure as well as iso, shutter speed. If they come out with a winner on the drone, great, if not, at least we'd have a great camera. They know cameras..... Time to expand their reach.
Also, it's not much of a stretch to realize that they' t kill the majority of the competition on service.
