With four threads all covering the same topic, it's hard to know where to post anything. But, I am curious about peoples' reaction to this thought.
If the 5D MkIII offers a "pro-style" autofocus, but if the sensor is essentially unchanged (no significant increase in Resolution, ISO speed, noise or dynamic range) will people buy it? Maybe throw in some bells and whistles, which this body seems to have.
That would be one way to differentiate between the 1DX and address the major concern/problem with the 5D II. Canon could easily do that and retain the same price-point as the current 5D.
