If you need to buy new and bigger CF cards for sports then consider getting the very fastest 90 MB/s cards such as the Sandisk Pro. It seems that they effectively increase the shooting buffer size substantially by clearing the data from camera to CF very quickly. StanJ reported 40+ shots in a burst of raw and then only 7 seconds to clear the buffer. I got less than 30 shots per burst with my 60 MB/s card and about 15 seconds to clear the buffer. My next card will be one of the 90MB/s cards because being able to shoot for at full frame rate for at least an extra second can be very handy.
The 1D4 raw files are bigger than the 1D2 cards because of twice the pixel count and further because of 14-bits per colour per pixel instead of 12. The use of oh-so-tempting high ISO bumps it up again.
