They also need a second card slot in the 7D. Canon really needs to work on low light and DR. I can tell you on my 7D, if you push the shadows much at all, you have some serious issues and it looks like that is almost the same in the 5D mark III. The AF in the 7D is already decent for a sub $2000 camera (especially compared to the 5dII, 8fps is freakishly fast, and 18MP is plenty for almost everyone, but I would love to see better looking shadows in any new sensor and better RAW noise performance because those are weak areas of the Canon.
