It looks like only the camera panning is set to follow, but still needs a pilot. It would be cool if the copter was also set to follow. You could program it to maintain a distance of 10' in front of you and 10' off the ground at all times. It would be like a robotic cameraman. I'm sure someone is working on it.
Not to change the subject, but what's up with the "rope-tow" style wake board facility? And, if there isn't a boat wake, can you still call it wake boarding?
