"Indulgence" is a good term in this context.
Leica stuff is priced at the (super-)pro level, but it misses features to live up to that. I have in parallel Canon lenses and body for that reason.
I am not sure whether this situation is a real commercial problem for Leica, since there are still plenty of people like myself who use and enjoy Leica R's and M's for personal work (with the exception of very few pro's using it indeed for pro work).
Now if Leica moves into medium-format, even that "indulgence" customer base will get smaller (some folks on this forum will be an exception, though...). In that case, they would need to move into real pro equipment territory, which will require several major improvements on their end...
(with a new user name, so please don't get confused; I am the OP of this thread).
