Speaking of real time GPU rendering, check out this demonstration of Octane being used for real time, photorealistic Arch Viz, on a RenderStream GPU render farm with 8 GTX 580 GPUs.  You have blurry reflections, blurry refractions, fresnel reflections, DOF, daylight system, and SSS, and unbiased path tracing, all at play in this example, with TONS of geometry in the scene, being done in very near real time.  Amazing technology and quality.

So don't think film studios aren't going to see the potential here to get photorealistic FX rendering at almost real time.  They are going to jump on this eventually too.
