Yep, the Karma will likely do OK but I see the Mavic selling at least 5X as many and maybe 10X. If the Karma does poorly, and it could, then GoPro could be done for. They had a good run of 5 years or so until others came into the game with much cheaper alternatives and for the last year or more they've been barely treading water. A failure of the Karma could kill them.
