Here's a link to a more appropriate forum. It is quite possible that Brazil and VRay find their way to the studios once they get more flexible interfaces (Brazil is supposed to get a RIB parser) - other non-mainstream renderers did so before, e.g. RenderDotC, Jig or BMRT. But I think by the time we have photon mapping as fast as Z-buffer is now, we will see a complete RenderMan implementation running on the latest commodity graphics hardware, setting new standards for high rendering speed. nVidia is aiming in that direction with cgFX and it looks promising.
