I was restating Harold's comment that it now includes an explicit Reference Medium Gamut, although I haven't read the spec...

Fuji C-fit looks very interesting. It looks like to me that by incorporating these colour "tweaks" they are attempting to build a system whose colour matching objective is "preferred" reproduction instead of a colorimetric match. I can see this being useful for a lot of consumer applications, where the image capture might not be the best quality, and the desire is simply for a pleasing result. But do you see it being appropriate in a professional setting, for the more sophisticated user?

I'd love to see those sample images.
