Exactly the camera I'm waiting for.
Same me! If it's 5d2 with a new sensor and 7d's AF, I'm in!
Comparing the image quality of RAW files from 5D Mark II and 5D Mark III, "new sensor" means pretty much nothing! Basicly you're in for 4 year ago's image quality with 3 year ago's AF.
I'm sick and tired of Canon playing mix & match with yesterday's tech!
We have seen a lot of comparisons between 5D Mk II and Mk III sensor. Sure, there is only a slight improvment in terms of high ISO in RAW. But I cant see too many out here complaining about it. There are improvements in other areas in 5D Mk III. The ultimate 2 things a lot of people complain about are: price and black illumination AF point. Price will go down in time and this AF point issue could be corrected via firmware.
But...for less than 2000 USD you expect 1D-X metring, 61-point AF, 8 fps (or more), new sensor ? Consumer (affordable) models are always about compromise. In time, pro features comes to consumer models...thats Canons habit I think.
...its the same like with cars: if you want luxury features, better (more powerful) engine - you pay for them. If you want latest and greatest - look for 1D-X or take a look at Nikon if they offer what you expect.
