That's silly. Screwdrive technology is efficient and far more reliable, and even better (as shown with the K3), if they improve the screw drive motor on the body, all the lenses benefit from faster AF, immediately.
I'd like to see *all* the lenses have both screw drive and SDM/DC, with an in-camera option to choose, for when you'd rather not be making any sound. (for that matter, I'd like to see a setting that lets you go silent/dark -- turn off all sounds, display off or dimmed to lowest setting, etc. I need to take the time to make a user mode that does that for me.)
