That makes me excited. I am looking forward to a more extensive review, but it is ironic that Roger compares it to a Zeiss, as I commented on another thread today that this lens physically/cosmetically looks very much like a Zeiss (a good thing, for me, as I am not a fan of the Sigma crinkle finish).
I'm interested in some head to head vs. the new Canon 35mm f/2 IS. One of these is going to end up in my bag. I'm leaning towards the Sig right now.
