It turns that the fancy Nvidia G80 chip taped out, and in working silicon stage it will have 32 pixel Shaders and, as predicted, have 16 vertex and geometry Shaders. Nvidia wants to stick with a two to one ratio and assumes that the games of tomorrow will need twice as many pixels than they will need vertices and geometry information.
Since this comes from the Inquirer, this is all speculation. 32 Pipes is along the right line though, so it’s not really surprising. The doubling of the Vertex Shaders is interesting though.
