I realized that you don't like the 5D Mark III for whatever reasons and that's is fine and you are entitled to your opinion but I know myself and a lot of others really enjoy that camera.
I don't want to warm up and repat the whole earlier 5D III vs 5D II discussions a few months ago (whereby I was laughed at when saying that the 5D III will be at $2700 end of this year - and it already starts now!). At least I can claim that I had a 5D III in my hands, and compared to my 5D II, I only saw the benefit of better AF in the MkIII. Picture-quality-wise, no difference - no surprise since it is fairly much the same sensor. When I purchase a new camera, I need to see a step up in resolution and maybe DR. Just for getting an improved AF system, I don't spend even $2500 for a new camera, sorry.
On the other hand, if somebody wants to switch to full frame now and needs very good AF, the 5D III is a very good option (especially if the price reaches more "normal" levels).
