Upsetting news, but predictable, I think. Film has advantages in medium and large format over digital (that's why I use it), but for low light, film has been losing ground for years.
This is just a process of nibbling away at the range of products in film, to stay afloat. The low speed films will be the last to go. People still look at my large prints (up to 30X40 inches) from large format negs and cannot believe the image quality. Digital shooters peer and go quiet when I tell 'em how they are shot.
Film will persist where it has strengths. Still, it's sad to see any of our choices disappear. Given what's been happening over the last several years, you'd think we'd be used to it .....
