Interview with Sony’s Toru Katsumoto
"We are also developing new models in the Alpha range. This year we will introduce some new models of SLR."
He specifically confirmed that there is a room for new Alpha 200 and 300 series (Sony a290 already leaked). Mr. Katsumoto also said that HD video recording for DSLR is currently in development but he doesn't have a set release date. Sony will continue to manufacture cameras with both APS-C and full frame sensors and the plan is to integrate 3D in their future camera product line (they added digital cameras to their 3D end-to-end solution few months ago).
In another interview Mr. Katsumoto confirmed that a firmware update will be released soon that will allow AF with an Alpha adapter on a NEX camera. He again expressed Sony's commitment to a 3D future.
The new Sony NEX cameras are available for pre-orders in various lens/colors combinations @ Adorama & Amazon.
