Like you I have been waiting and trying to decide. I was hoping Canon might upgrade the 5D at PMA, but no-go. Trying to guess/predict what Canon (or any other camera maker) might do is about like second guessing the stock market I suppose. The 5D was introduced in August of 2005, so it will be at about 24 months this Fall - and one might assume an upgrade will be in order. On the other hand, the 1DsMKII is working on three years since upgrade?? (I think that's right?) One wonders of the camera manufacturers will begin slowing their releases/updates as the technology stabilizes.
