Not so much Gopro drone is announced as Gopro have confirmed what everyone already knew - they intend to get into the drone market.
There are no details, not even any indication they have started to work on it.
Just that they plan to release a drone before July 2016.
I interpret it with a bit more optimism, to me it reads as; "rumors are true, we've developed a quadcopter and plan on releasing it next year. Watch for further announcements."Yes .. that's why I said they haven't announced a drone.
There is no gopro drone to announce.
They are announcing that they intend to make one.
