What I'm hearing so far: 1D MkII replacement will have a stop of noise advantage, 10 MP, 10 FPS, better AF... 1DsMkII replacement will have a new lens mount? Medium format sensor? 30D replacement will have lower noise, more MP, better dynamic range... 5D replacement - I've heard nothing except a couple rumors of a lower priced full frame option Lenses: 400mm f5.6 IS, 24-70L IS, and 100-400/4L IS are a few I've heard about. I suppose they'll need some lenses for the new mount/medium format. Any other rumors of note?
