Even if the new lenses do have the drive shaft, for how long will this be the case? Will Pentax eventually drop the AF drive shaft, just as they dropped the mechanical aperture linkage from many recent lenses?
How many years did they support the mechanical aperture linkage even though the cameras and lenses they were producing no longer needed it? If you want to use that as a reference you've got, what, 20 years left? 25? When did the A-series first come out?
