While raytracing might free developers from using DirectX the problem comes in the fact that even with CPUs with 8 cores they can't match a graphics card at running today's games. That means that until we hit critical mass where CPUs can do everything that a graphics card can, we can't play older games that don't use raytracing. It's the chicken and the egg problem and that's assuming that graphics cards don't become more and more advanced increasing the difficulty.
Obviously Intel is going to push for raytracing as the primary method of game rendering since it would increase their market share. I doubt Intel's dream will happen but at the same time raytracing would alleviate a lot of problem. A hybrid approach will probably emerge sometime in the future.
