Two thing that seem promising me to me are the edge smoothing and the seperation of diffuse and specular in the lighting. If I'm not mistaken the smoothing is based on an angle, like the way UVMapper Pro uses an angle to split welded vertices and allow hard edges. This feature will let you pick the angle (usually less than 45 degrees)that the smoothing oocurs. Less than the number and the edge is smooth, greater and it is creased. The neat thing about the lights is now I can finally do the neo-tokyo renders I've always wanted where there are dozens of specular highlights without having to worry about washed-out diffuse lighting. Throw in the point lights, and P6 is going to be the bestest!
