as for why they have not yet released a 1Ds3, there are two reasons, #1: the need for them to give enough time to 1Ds2 owners to absorb the cost of their original purchases. #2, there seems to be an issue with the developpment of the 23Mp sensor... which is what is intended for the 1ds3. there is NO need to come out with a camera that has less than 23Mp as manufactures of 17-25Mp mf bodies (leaf in particular) have had DISMAL sales because of 30+ mp systems.
There have always been two 1D lines - one for photojournalists that is fast (and 1.3x crop), and one for glossy magazine photographers that is high res (and full frame). The 1D MkIII is the latest photojourno camera, and 10Mp is plenty (newspapers can't even use that much resolution. That's probably the reasoning behind sRaw). The upcoming 1Ds MkIII will be the next generation of the other.
Giving 1DsMkII users time to absorb the cost? The 1DsMkII is already the oldest current digital body. (And what about the 1D MkII N owners? They only got 6 monthes to absorb that cost!)
I don't agree with your assessment on 17-25Mp vs 30+Mp - you are talking about medium format, and there's not as much cross-over between the 35mm format and medium format as people would like to think. What you are saying might be applicable if there were a 33Mp 35mm format camera, but there isn't, and there's not likely to be in any hurry. When the 1Ds MkIII is announced it will be the highest res 35mm format camera, undisputed king of the hill.
