XJEEPER, I have a contact at GoPro. I had to talk with him about something else, but mentioned the remote control feature.
Their cameras, unlike their competitors, have a "piggyback" port on the back of the cameras. They are set to release an extended battery and LCD screen in the next couple months.
I previously recommended a GPS module. I mentioned that I saw a request for a remote control as well. He says almost everyone in the company is in to some type of racing or extreme sport, so they are well aware of the desire for a remote control to control the cameras.
