I hope so too. Since about 2001 I've shot Leaf medium format backs on primarily the Fuji 680lll. I'm a studio product guy for the most part and need the ability to use the Scheimplug principle. Short of a technical camera, the 680 works well and the lenses hold up.
And while the medium format back still puts out a beautiful file, it is hopelessly behind the times with ISO. I know it ain't going to happen but would love to see Fuji do an interchangeable back somewhat reasonably priced...of course.
