SR1 will have a new licensing system with a license server. This makes V-Ray more usable in larger studio's, since licenses can be shared and administered from a single location.
By the end of this year V-Ray for Rhino will adapt more of the features that are currently available in the 3dsmax version of V-Ray. There will be toon rendering, ambient occlusion and progressive real time rendering preview, which will aid in setting up a final rendering without having to make numerous test renderings.
In terms of interconnectivity, there is more to look forward to. Especially large studio's will benefit from material and scene exchange between packages. ASGVis's material format .vismat and V-Ray's .vrmesh will make it possible to let (parts of) scenes be created in Rhino and be rendered in 3dsmax or vice versa!
