Paul, The Canon 1D is actually 8 frames per second and whether it 21 in the buffer or not doesn't matter to me--I've never run into it in actual practice. I remember that when the D30 was announced, the 3 fps rate was attributed to the relatively slow speed of the CMOS, something the 1DS shares. While I agree that the larger file sizes require a greater data flow rate at the same frame rate, Canon so far has solved the dilemma with faster processors and by splitting the sensor chip into halves for two processors. What is to prevent four or sixteen processors to be used? (Arrr-Arrr More Power!) I look for the 1D replacement to have a larger sensor, megapixel rating, and still maintain the frame rate and buffer capacity. Mind you, I'm not predicting when.
