Bryan Carnethan has a very favorable review of the new 35mm f/2 IS up now:

Most interesting is that he concludes that the bokeh is smoother on it than either its predecessor, the 35L, and the new Sigma (which he makes second).
The biggest advantages of this optic over the Sigma:
1) The very effective IS (he calls this the most handholdable full frame lens available), particularly for video purposes.
2) Much smaller size and weight.
3) AF is (according to Brian) amongst the quietest he has heard (which definitely sets it apart from the old 35mm f/2).
Biggest downsides (vs. Sigma)
1) Slower aperture
2) Slightly lower sharpness.
I'd really love to see a head a to head comparison between the two lenses. I will probably add one of them to my kit within the next year, and I'd love to see them compared.
