Google Glass Takes Awesome Quality Videos – is this the end of the GoPro?

I had the opportunity to ride the SkyWire (the largest and fastest Zip Wire in England) at the Eden Project last week, and took Google Glass with me to record my flight.  When I got back, I was so impressed with the footage recorded I created this short movie showing my trip (includes brief footage from an iPhone).

What subsequently struck me was, if the video quality is this good, is there that much space left for the GoPro for the hobbyist?  The video quality and battery life are only fractionally better, and those benefits cost you a device that’s much more bulky and that actually requires a hand to operate!
