In my opinion in order for gaming to really emerge as the top media gameplay footage needs to evolve. Developers could include a recording feature that would take advantage of cyberspaces ability to have an omnipresent camera. The ability to capture any shot along with some simple editing tools (including voice over, sound fx, etc) would not only bring a new a dimension to gaming as a spectator sport, but would elevate cinema by giving millions of users the chance to create and execute their stories. A kind of primitive art movement if you will. Just look at what red vs. blue has done off of a glitch.
