I voted for the 5D mkIII. I really want to get a full frame camera, but can't afford the 1DS mkIV. (Although I must say I am very curious about that camera...it is probably my second choice). I know that I can afford one of the 5D cameras. I am hopeful that the 5d III will have a faster/better AF as that is the only thing that has held me back on the mk II. If the Mk III comes out and the AF isn't improved, then I know that I won't get a better camera for a while and I will just get a mk II as they will definitely be cheaper at that point.
The 60D will definitely be in my price range, but I am really tired of using a crop camera. Every time I use my friends 5D I am reminded of how much I want a FF. I am kind of curious about what kinds of goodies it will have though.
Now a mythical 3D would be nice, but we really don't even know if one will ever come out. It seems like more of a pipe dream with specs that people keep making up. Seems like everyone keeps giving it all of their dream specs. Don't get me wrong, if Canon made a camera with all of those specs, I would love to have it, but I think I would go crazy waiting for it to come out. With the 5D III, we know it's coming, it's just a matter of when.
