Maybe. It would be a nice option -- it's
inconvenient to have to switch the lens to manual
to override autofocus, and on too many lenses, you
also have to switch the camera to manual focus.
AF speed isn't as important an advantage with most
lenses.
The problem is that that bit of functionality won't
increase the worth of the lens as much as Nikon
would increase the price.
If Nikon wanted to stay even with the competition,
they'd have to replace their pro-grade lenses with
AFS versions, at a price not more than 10% above
the current version.
I'm not foolish enough to believe that there's any
chance that that's what Nikon will actually do, so
I expect the change to AFS will happen slowly, if
it happens at all.
Still, it's not a big deal. I'm more concerned with
the glass than with the bells and whistles -- otherwise
I'd have jumped ship a long, long, time ago.
