you started this thread by saying that there were a lot of A mount lenses out there, and the also talking about sharing components.
Maybe I read you wrong, but my reply is based on thinking that electronic components and design R&D can probably be shared between the mounts - you shouldn't need a whole new CPU just because the same/very similar sensor is in different bodies, even if one is E mount and one A. Granted, having electronic aperture instead may mean a different output signal goes to the lens, but in reality it's probably going from the CPU to a secondary component that's doing the actual activating. Likewise focus sensors could be shared, as well as other components.
The problem with the lens design, however, is that E mount lenses, with their very short flange distance, are more like rangefinder lenses that traditional SLR lenses in design. DK had a whole section on this somewhere that I'm too lazy to find!
Sony is a big, rich, company, but like all companies they want to keep costs down and make profits. If A mount becomes unprofitable, it will go bye-bye!
For me the success of the E-mount, improves the chances of the A-mount staying alive. As cameras become increasingly electronic, both ranges of cameras can share the main (and expensive to develop) components. The A99ii and A7Rii(i) can /do/ will share sensors, shutters assemblies, Bionz processors, EVF, TFT screens, possibly the IBIS mechanism. The R&D costs of the A99ii were probably pretty small as it uses a mixture of present and future E-mount components and can probably make a profit on fairly small sales.
