So thats one vote for ech so far, ive read that the 1Ds suffers with noise in fairly low iso, i think the 5fps would be enough as i never really use the rapid fire of my 1D mk3 , the 21mp would allow for great cropping vs the new tech in the 1D mk4, 16 mp so still grood for cropping, lightning fast AF, and a bit of cheeky video to boot. This is going to be my last big spend on a camera so need to make the best choice........
if it is your last BIG camera purchase I'd go for the 1D mkIV, it'll remain more up to date longer, especially with the likes of high ISO and HD video - is there a substantial price difference?
