I've kind of wondered about this a bit too. The respective visual quality side of it that is. Especially in a context where you're actually playing a game. You're not just sitting there staring at side by side still frames looking for minor differences.
What I have assumed given then trend, but could be completely wrong about, is that the raytracing version of the world might be easier on the software & game dev side to get great visual results without the overhead of meticulous engineering, use, and composition of different lighting systems, shader effects, etc.
