Hmmmm ... what I'd like to see 1) 16-bit/channel RAW mode with high-speed lossless compression. 2) Increased array sensitivity range (ISO range up to 12500) with an across the range reduction in noise. 3) Sports viewfinder (>100% coverage). I think the Sigma SD9 has one (although I've seen at least one review say it has a 98% Horiz/97% Vert coverage). 4) Full frame CCD/CMOS/Foveon sensor. 5) Good weight. Minimum 600g, I seem to prefer cameras in the 700-1200g body weight range. EOS 1DS felt kind of heavy to me at almost 1600g. EOS 10D and Nikon D100 feel just about perfect. Small and light might be great for taking snapshots on vacation, but I want a camera that has a good, solid feel to it and fits well in my hands. I can't get a solid shooting base unless I can get the camera to sit right in the palms of my hands. The weight is what helps me to stabilize my shots when I go handheld. I'm use to shooting with cameras like the EOS 630 and EOS 3. A 100g camera is not going to cut it. 6) Better weather proofing. Yea, you can take the EOS 1D and 1DS out in a rainstorm or sandstorm and they are sealed like tanks. But they also cost like they're tanks. Want to see better weather body sealing in high-end prosumer cameras. 7) Built-in infrared mode. 8) True TTL flash modes. There's probably others that I can't think of right now. :) -=>Donald
