Kevin I have given up trying to predict what Sony will do
However, I would not be very shocked if the next round of entry models had no AF motor in the body (A2xx-3xx series)
On the other hand Sony would want to start putting AF motors in a fair few lenses, else they could cause themselves some problems. For example CZ 16-80mm (SSM would be better) 16-105mm another upgrader APS lens, maybe even the 50mm f1.4. Some predict a re-vamped 75-300mm lens with built in motor too
If we start seeing that happen, it's almost a sure thing. Currently though, the vast majority of lenses are screw driven. Will be interesting to see how Sigma and Tamron respond as well.
This strategy is not without problems though, it starts to make those vintage Minolta lenses far less appealing if you have no AF on a body. Maybe Sony want people to buy their lenses, but they cannot make them, as 3rd party manufacturers have offerings.
