If it gets 2 stop improvement in ISO over the mk2, that means clean shots at 6400, and would most likely be enough for people to upgrade, however its reasonable to assume that we will also see improvements in metering/dynamic range, perhaps some other minor things. But you definitely won't see a great AF system on a 5d body, not now, not ever....so please don't expect that. Save up for a 1D-X![]()
The problem with this sort of rationalizing is that while a 5DIII with an antiquated AF system might make sense for product alignment within the Canon family, it will also be competing for market share with the Nikon D800. The D700 already crushed the 5DII in terms of AF (51 points vs. 9) and speed, but the 5DII's significant advantage in resolution was enough to win over many buyers. If Nikon comes out a D800 that maintains its AF advantage over the 5D, but then makes up for the D700's resolution shortcomings with its long rumored 36 megapixel D800, Canon runs the risk of losing market share to Nikon.
