It's always good when the plague known as x86 doesn't encroach on any new areas. Why Intel thought an instruction set considered poor 32 years ago, made sense for a modern GPU escaped a lot of people, considering compatibility wouldn't be such an important consideration there.
They'd be better off going with a clean, efficient instruction set if they ever try to get into that market again. How could they expect to compete with well-established players with that handicap?
I still don't know exactly what "we are focused on processor graphics, and we believe media/HD video and mobile computing are the most important areas to focus on moving forward" means. Processor graphics means the IGP that comes with the processor now? The other stuff also means that, even though discrete cards do that too? That's got to be it, but it's not too clear, really.
