I think we're lucky to have the lenses we currently do. M lenses are such a specialized market, it's amazing the ZM line exists at all, in my opinion.
Now if the M9 stripped away it's 'red dot premium' was actually being sold to people who could use it to realize their photographic aspirations, I'm sure Zeiss lenses would fly off the shelves. Sadly, only the very rich, very well established photographers, and Seal, get to use it.
