Doubtful.  The difference in speed is just too great.  Sure, you could
raytrace an image that looks incredible, or scanline render an image with
100x the number of moving objects on screen at 4x the resolution.  We'd have
to get to the point where raytracing could operate at 60fps with hundreds of
objects to make people give up scanline rendering.

I don't think it is unlikely for raytracing to be used in games 
eventually. Remember, the whole frame doesn't have to be raytraced, they 
can use it just for reflections and transparent objects. I wouldn't be 
too surprised to see a checkbox for "True Ray-Traced Reflections" 
instead of environment-mapped ones. (for big, flat reflections like 
floors, even environment maps aren't necessary, but for complex objects 
or curves...)

It won't be any time real soon though, there are too many other things 
that need to be improved. Mainly physics and more detailed environments.

Actually, the XBox game "Project Gotham Racing" uses real reflections on the
cars, but it only updates at, say, two or three frames per second and the
resolution is rather low.
