I am aware of the fact that this thread is quite old, however it seems that there is no conclusion here. I own S-Works Toupe (https://www.flickr.com/photos/45810898@N02/6831774623) and new Specialized Toupe Pro, so they are hard to compare. The old SW has less padding and different shape. Anyway, the only difference between new Specialized Toupe Pro and S-Works Toupe I've found is 4g less for SW, the rest is the same.
