The RZ series may very well have been intended to eventually replace the RB series, but not immediately.

With the RZ series you lost functionality in some areas, while gaining in others. It certainly didn't make the RB series equipment second class.
very interesting ! Didn't know these data. But why didn't they made it interchangeable to the RZ ?? So can I use my RZ lenses/backs/viewfinders on a RB body ? I would love to have a full mechanical body next to the RZ ! At KEH there is a Pro SD Ex+ for $139,00 !!!
