Ken Rockwell's speculation:

Originally Posted by Ken Rockwell It's almost identical to the D70s in most regards, except: 10 Megapixels, up from 6. Works fine with old manual focus AI and AI-s lenses in A and M exposure modes. Tiny possibility it may also allow P and S exposure modes with manual lenses. 2.5" LCD, up from 2.0" 4.5 FPS, up from 3. 1/250 sync speed, down from 1/500. Top panel illumination now switched on by twisting the power button, just like D200, D2X, etc. The D70 had a separate button. The D80 is an improvement. Takes SD cards, not CF. Rotary, not slider, viewfinder diopter control. Slight rearrangement of buttons on rear. Dedicated AF selection button on top of camera, a big improvement from D70 which required a menu to select between AF-S or AF-C. Price: $899.
