One further note. I was able to edit the exif on a X-T1 file using exiftool, the windoes GUI version thanks to a tip from Graham Welland. Exiftool by itself is command line, and I am not that good with command line anymore. However there is an excellent GUI that you can download that uses exiftool and allows you to see the file in a excel like look.
All that has to be done is edit out the camera name, from X-T1 to X-E2. It's the same sensor. Capture One will now open the files and it looks great with the X-E2 profile. All the other info works fine, i.e. aperture, lens info, WB, etc.
This is only a work around, but I don't think Capture One will be getting around to another update from 7.2 for a while. Maybe wrong, but I base this on their usual timeline.
