I was just getting ready to update my Capture One Pro to version 8 but discovered that it doesn't support Mountain Lion. Well, that rules me out for an upgrade for the foreseeable future. I had to upgrade from Snow Leopard to Mountain Lion last year so that Lightroom, etc would be supported. Not a great way to keep Capture One customers coming back. As I see it, and I may be in the minority, that professionals that develop a workflow, don't necessarily want to change things when they are running smoothly with their current operating system.
