Pro Photographer Kazuhisa Nishikawa has posted a Nikon D1 vs. Canon EOS2000 (AKA. Kodak DCS520) comparison gallery. This gallery features portrait shots of Japanese model Sachie Koike.

For me it's pretty difficult (especially without the original full-size images) to say which is better but the D1 does seem to have a little more "depth" and feel to the image.
