Chalk up another one for replaceable focusing screens in the 5D3. That was an unforgivable omission in a camera at this level. Most of our stuff is manually focused studio work so we have to fall back on either 5d2, 1d series or medium format bodies, which is not always ideal. My old eyes need all the help they can get.
Would love to see the new rumored TS-E 45 & 90 appear with the same features and resolution as the 24.
Oh, and one of those Manfrotto tripods, please.
Now for the fantasy stuff - what I'd really like would be a simple, ultra-high quality, manual only, full-frame 35mm body with mirror lock and knurled rotary knobs on top for shutter/aperture/ISO. Nothing else - no autofocus, no fancy electronic stuff that needs a one inch thick manual. Like an old F1, but digital. Don't even need an exposure meter. It would probably have hairs sprouting from the hand grip.
