I for one will be watching the ZI very closely. If it were not an M mount, it would be a different story, of course, but the 28mm framelines and long rangefinder base are worth a lot to me. I agree that the first year (give or take) will be very important wrt reliability, alignments, other adjustments, fit and finish/overall quality, feel in the hand, etc.

I wonder if Zeiss has written things into their contract with Cosina to protect the brand by prohibiting Cosina from transferring the tooling, or features into a Bessa-badged product.
