Well actually the software is not new but PhotoNinja by Picturecode have added raw support for the Fuji X-series with a their own new demosaicing method that they claim is supposed to work better. I was going to try it, it is in pre-release and the download can be found here:http://www.picturecode.com/download_prerelease.php
The claim a reduction on the chroma smearing. It might be some deconvolution being applied, not sure. Nice to see options although I am quite happy with C1.
