I really, really, really, really, really hope Sony is not that stupid to remove the screw drive off the entry level cameras. While it's true that most users of that kind of cameras never go beyond the kit lens or lenses (like the DT 55-200mm or 75-300mm), it would severely limit the options of lenses they can mount and use with AF.
It's also true that users of that kind of cameras rarely bother with MF, so if they mount a Minolta lens and they got to focus it by hand, they won't like the idea.
Sony shouldn't be so arrogant to think that entry level users would only mount Sony lenses, it's easier to find a cheap Minolta than a cheap Sony.
If I ever need a back up body in an emergency and I can only find an A37, that means I'm royally screwed, since so far, all my lenses are screw driven.
If Nikon hadn't removed the motor from their entry level models, a lot of users could actually use their Nikon legacy lenses, which sometimes are found for cheap rather than the new and expensive ones. I know three dudes that haven't bothered getting another lens for their Nikons because they can't afford the new models and the old ones they could afford, but none of them want to deal with the MF at weddings.
Sony, seriously, if you're going to copy Nikon, let it be the good things: image processing, NR, JPEG output, in camera options, copyright coding in the EXIF, that kind of stuff.
If you're just going to be "Nikon lite", I might as well just go to Nikon for crying out loud.
