If Canon ever reads these things, I hope that the year or so time before the release of the high (85?) MP camera gives them time to consider adding these 4 features to it:
1) Add an aperture-bracketing feature.
2) Embed Arca-Swiss compatible grooves on the bottom front & back edges so that you can mount it on tripods/gimbals with quick release clamps. This wouldn't take up hardly any space at all.
3) Add a GPS feature to store location in exif data, and enable it to be used in a low-battery-drain mode so it has minimal impact on battery life.
4) If you have one fast and one slower card slot, then allow an option to store pictures to the fastest card slot and then, in unused background time, copy the pictures to the slower card slot. Even if you have 2 identical card slots this would still be helpful to allow maximum record speed to 1 while still allowing background store to the 2nd slot.
You've got a year or so to add this if you want, and it would really make a difference to me, and hopefully really pleasantly surprise others, too.
