I guess I could have and should have elaborated more on my thoughts here. It boils down to two forecasted models:


The 1D Mark IV, to me, doesn't make sense as a 16mp FF camera. Although the pixel density matches its predecessor, leading to great noise performance and diffraction threshold, I don't think FF@10fps is "easy" (and therefore feasible at the 1D price point). To get 10fps, the 1D3 needed two mirror motors, one down and one up. Most every other moving-mirror camera uses a motor and a return spring. Having to motor a FF mirror both ways at 10fps would be tough. Is the 1Ds3 a testament that it can be done, since the viewfinder blackout is (I think) the same? I don't know, but I doubt it. They also have more revenue with which to solve that problem, since the 1Ds is in a higher price category. There would also be sacrifices in x-sync speed with FF, a trade-off that likely doesn't make sense in a "reporting" camera. Speaking of, I see some challenges if Canon had three FF cameras at the existing (5D, 1D, 1Ds) price points.


The 60D, to me, doesn't make sense at APS-H. Losing the EF-S capability means the widest effective focal length "loses", as it shifts from 16mm EFL (using the EF-S 10-22) to 18.2 (using the very expensive 14/2.8L prime). Folks with earlier two-digit (xxD) cameras aren't going to want to obsolete their EF-S inventory with a newer camera in the same family. If it were a 7D model, it creates an interesting three-tier line-up: gripped/rugged bodies (FF and APS-H), non-gripped bodies (FF and APS-H), and EF-S bodies. Whether that makes marketing sense is left to Canon: if we figure that the APS-H body costs about 57% ($4500 vs $8000) of the FF body, the 7D would be about $1550, and that'd be too low for them to make it a pro-caliber unit in my estimation.


When I looked into my crystal ball a year or so ago, I saw my future with two 1D bodies and one 1Ds, before eventually shifting towards two 1Ds bodies and one 1D. I see that working out, whether the 1D line stays APS-H or goes FF. Thinking about it though, a 5D/7D-type combo might work well for a lot of folks too.
