Is there any chance then that a new 5D III at least have a better Servo mode AF? I mean I know it is supposed to be a studio and landscape camera, but I bet you a good portion of the current 5D buyers are amateur enthousiast and from time to time it would be nice to be also able to shoot moving targets like our children with that camera.
Currently my 5D II does not do that well at all. I know I could buy a 7D for that or wait for the 1DX, but without a full blown pro level AF, I would be happy with a new 5D III where at least the center sections as a wider and improve Servo AF performance.
Sure, there's a chance. There's a chance pigs will fly, and a chance it will snow in hell, too.
Ok, I exaggerate. Apparently, Canon did have that in mind with the original 5D. As I mentioned, the 5DII came out after the 40D, the latter having 9 cross-type points vs. just the one of the 5D/5DII. I recall reading a statement from Canon (not sure where) to the effect that they considered using a 40D-like AF sensor, but decided to stick with the sensor from the original 5D specifically because the 6 invisible AF assist points resulted in better AI Servo performance. Granted, if the 5DII's AI Servo consitiutes 'better
'..... I've never used a 40D, but I wouldn't say the 5DII is substantially better at tracking subjects than the T1i which I started with, and people who've used both 5DII and a recent xxD have claimed the tracking is better with the xxD body.
But the point is, some within Canon do recognize that a decent level of AI Servo performance is needed - after all, it's not jsut a studio/landscape camera, it's a wedding camera, too...and brides do move (just not very fast). But it will remain a fact that if you want an AF system that will deliver the best keeper rate, you need a 1-series body.
