There are some shooters who would like 8fps AND full frame. This means at the same time in the same camera, not simply buying a 1D and a 5D.
I shoot alot of sports, from World Cup football, The Olympics etc to everyday Premiership matches and all the sports snappers I meet say they want full frame, many have already jumped to nikon. The idea that sports snappers want cropped cameras is a myth. A cropped camera has no further reach than a full frame camera of the same pixel density.
Also, cameras are now mini computers, why don't canon make the most of this? Why do we have to choose between TV,AV etc, why can't we make our own settings? Let me explain: Take a full spectrum of exposure, from the darkest to lightest and throughout that spectrum select the mode you want the camera to be in.
For example, at a football match, thats played in the evening as the sun goes down and the floodlights come on... you might decide to start at ISO 400 and F4 and let the shutter speed come down, when it reaches a level you previously selected, say 1000th, it stays there and another setting changes to make the exposure...perhaps you chose the aperture, which then automatically comes down to a level you have chosen, say F3.5...Then you might have decided the aperture should change again, or perhaps the ISO should go up to make the exposure, the camera will follow whatever you preset automatically...
This means the camera will always select what you have decided are the optimum settings for the light level, rather than merely changing just the shutter, or just the aperture...People will then be able to share their favourite settings online too.
I know you can do this in the camera manually, and its possible to do so as the sun goes down, but imagine a game thats played half in the shade half in the sun, its not possible to change the settings fast enough in that situation and you are left with deciding what the minimum shutter speed, or aperture is that you will be happy with, a massive compromise really.
Canon, design the next camera for photographers, or better yet, let photographers design the next camera.
