I don't see raytracing ever becoming the mainstream for games. People have been predicting it for well over a decade and it's never gained any traction. For 3D Visualization, sure, but it would be a step backwards from where we are today to move to raytracing. The current generation of videocards have much more power than the last generation, like the ability to create geometry on the fly. It wouldn't make sense to tear that all down and start again. It wouldn't make sense to retrain every artist and programmer from scratch.
Ultimately though it will depend what the big players like EA and Ubisoft want. If they want change, they'll probably get it and if they don't, they almost certainly won't. Now how often do you see EA in favour of major change?
