No one can say how long it takes until the support for new cameras in CameraRAW/Lightroom is available. And Adobe doesn't say anything about a release date for the next update.
In the meantime you can use the software form the camera manufacturer to convert the RAW files into the DNG or in 16 bit TIFF format. This formats you can use in Photoshop and/or Lightroom. If Sony supports DNG I would prefer this format.
