There are some scenes that cry for color but are shot in B&W. A beautiful field of coiled grasses becomes bland in B&W but would be beautiful in color. I see this so many times on APUG. Don't forget color!
As for in the future, if Kodak and Fuji left color, it would be for a reason. That reason is cost and ROI. At that point it would be futile for Ilford to enter color.
