I'm fairly easy to please. What will make me upgrade my 7D is:
- Clean shots at up to ISO 1600
- Dual slots, both SD would be nice, but both CF is fine. Just not one CF/one SD
- 5D III AF. Although I'm happy with the current 7Ds AF, the thought of having even better perf would be sweeeet
- Same layout/ergo. If they change it too much I'll be unhappy, an integrated grip will be a deal breaker.
Not fussed about GPS/WiFi or a touchscreen or even an fps upgrade.
