GPUs Set to Increase Performance by 570 Times by 2015

[NJ5]

@Slimebeast: Remember that the 360's GPU uses unified shaders, so the 500 million polygons per second are only possible if the game isn't rendering any pixels.

Divide the capacity between vertex and pixel shaders, and you get a quite smaller amount (dependant on the game of course).

At 60 fps, it's a theoretical maximum of 8.3 million polygons per frame... and then reduce that further to account for the pixel shaders. In the end you aren't that much above the number of pixels.
