One of the issues with being an early adopter is RAW support. Capture One supports the S1rII RAW files, but that's it as far as I can tell. On the other hand, support should be fast in coming, because based on my tests the S1rII raws are encoded in the same V8 format as the S5II. I downloaded a raw file from the S1rII (available at dpreview) and used a hex editor to rename the camera from S1RM2 to S5M2 (but only in the first location where it appears.) I then opened the modified raw file using RawTherapee, and it worked great. The default color and exposure settings matched the settings from the jpeg very closely, and I experienced zero issues editing the file, including more advanced edits such as changing the demosaicing algorithm. I was also pleased to see that the EXIF info in the resulting image correctly identifies the camera as the S1RM2, which results from editing only the first instance of the camera name.
