You can only hope that the next update will include support to your camera. If you are dependant from Lr support you should check first if the camera is supported.
A workaround could be using whatever Sony offers and saving as a 16 bits TIFF. May be (but I doubt), the Sony tool also supports exporting to DNG. That would be a great format as a replacement. TIFF is only a workaround not a solution...

My experience is that the companies want to stick with their format...
If you are very knowledgable, you may also try to path the files so that they report an older but similar camera. Very often, camera makers do not change a lot in their file formats. But as Adobe isn't sure and they want to produce correct results, they do not support unknown models.

No one can say how long it takes until the support for new cameras in cameraRAW is available. In the meantime you can use the software form the camera manufacturer to convert the RAW files into the DNG format. This format you can use in Photoshop and/or Lightroom.
