Nothing can kill OpenGL, if DirectX couldn't do it, certainly not this proprietary shit.
Android based phones, tablets, consoles and even laptops and dekstops (yes, they are coming and they are getting better very very fast) all use a simple version of OpenGL. You'd have to kill that fast-moving train to kill OpenGL and that is not going to happen. Yes, AMD got a big win with it being the base of the new XBox and Playstation toys. That would have major implications a few years back. I'm not convinced it will make such a huge difference today. As I said, there are Android consoles for sale right now and more are coming. These android consoles won't have the horse-power of the new XBox / Playstation things, but it really won't matter. Also note that there will be one XBox and one Playstation but there are already dozens of Android consoles to pick from.
