I think it's the coming direction for videos, and apparently for stills as well from what I hear from photographers. As I think of what I go through to be able to video all the angles I'd like to show from a kayak, 360 solves a lot of issues I've had to work around.
Plus, quality of some of these new 360 cams seems better than the current range of fixed view cams, so even if you and viewers don't use the surround view format, you still get a great experience.
Only drawback is the stitching and editing software, which some brands appear to have solved well.
Oh yeah, the price! But while Fusion is in the higher end of new non-pro cams in price, there apparently are quite a few contenders at mid and even low end of pricing, if you watch the YT reviews.
You know, B&W artistic photographers said the same thing about color when it first became commercially cheap for consumers, and still photographers said the same thing about consumer video, and film photographers said the same thing about digital. Look where we are today and you realize you cannot stop the march of technology and change.
I see this as a good move for the market and for Gopro. Too bad Nick didn't do this earlier instead of wasting time and money and reputation on forays into the "toys" market, where he didn't belong.
