My MkII won't be discontinued for the foreseeable future, thanks in part to my 7D
I love the way the MkII and 7D complement each other. In my eye, a choice can be made between either the both of these camera's vs 'only' the 5D mkIII that combines their functionality. I strongly prefer to have two bodies however with different capabilities - always the right tool for the job and the possibility to carry both bodies with different lenses for different focal lengths to save swapping out lenses.
