A digital SLR like this: indexed ISO adjustment wheel for the right thumb, shutter speed dial, manual/aperture-priority modes and only-auto white balance, two-position light-meter switch: matrix and weighted spot. Push-button 12 second timer, manual mirror-up mode. No external display, only an in-viewfinder needle light meter and small lcd counter on top for pictures-remaining. Super long battery life and well padded circuit boards, gasketed metal body.

Pretty please!

Oh yeah, and if it could look like a Nikon F3 or a Leica III series, without looking like it’s trying to look like a Nikon F3 or Leica III series, that would be a great plus.

Edit:
And if light meter needle could have little tick marks +/- EV in thirds, up to one EV, that would be some seriously wonderful frosting on the cake.
