I have no idea on the date of the new 5d, but I am willing to bet it will have live view, 5-8FPS drive, 6400ISO, wheather sealing, 14-16mp or so, and a 3" screen. Basroil mentioned the D3. The D3 is a different camera compared to the 5d. It is more a speed camera, where the 5d is all about detail. I once saw a test on here (I cant remember the thread, but someone will) of the D3 with 24-70mm F2.8 Nikkor and a 5d with the same lens on a converter. The 5d had more center sharpness (since an optical converter was used it hurts sharpness, thus saying something about the 5d), while th D3 had better corner sharpness( it was again because of the converter on the FF edges.) I really think that Canon has the 5d in a sweet spot in the camera world. Not too out of the price range ($2900 vs 5000 for the 1d), excellent image quality with a good feature set. All in all, a good camera. I do how ever think that Canon will update the thing with what I mentioned above, simply because people have always complained about the lack of these features that the higher end cameras have. And it not being updated in over 2 years.
