I guess it's just a prediction. From gopro 5 to gopro 7, Gopro didn't make any blockbuster upgrades, but everytime DJI lauches a new product, it not only poses threat to other brand, but also to its own products, such as Mavic2pro vs Phantom4pro, Osmo Action vs Osmo Pocket.Curious as to how DJI can be claimed as “taking over the top position in action cameras” after less than a week of sale. Information somewhere that I haven’t seen?
