Extra AF sensitivity only with center point and only with f2.8 lenses? They won't do that if they port this AF system over to the 1 series, it's a bit consumer still, still means that focus accuracy with moving subjects and f4 lenses won't be up to 1 series standards. Big shame that personally, it's a real issue for me when shooting dancing and the like, the f4 lenses just don't lock on anywhere near as accurately on a moving subject as the f2.8 and faster lenses do. If anything I can see this as a reason why the 1 series is what a pro sports photographer will still buy. yeah they should've at least tossed us the f/4 high-precision for the center since it does make all the f/4 dodgier for AF. Although, then again, perhaps AI Servo doesn't really work that way anyway and if it has good logic and the same base sensor point (just one shot f/8 and f/4 precision turned off in firmware?) maybe it won't make any difference at all??
i imagine the 1 series will have at least a few more f/2.8 points as well for better precision for alternate framing
I'm not ready to believe that firmware will be the main difference between the 7D AF and the AF in the next 1-Series, although we can hope!
But I agree with where you're headed, i.e. just because we don't have high-precision at f/4 doesn't mean the new 7D AF won't still be much better than the xxD AF at f/4. It may not be 1-Series, but it may be close enough.
