I think I may be alone in thinking the majority of those 5D III specs are totally bogus. The 22mp sounds plausible, but 61pt AF and 7.5fps sound FAR more like wishful thinking or even someone trolling with rumors to see what kind of response they get. I don't think, logically, there is any way Canon would cut into 1D X sales by stuffing such an advanced AF system and high frame rate onto the 5D, which has classically been positioned for a very different market.
WISHFUL THINKING! I'll take the 22mp over 18mp, though.
