I think that while film has a bit of a comeback due to its nostalgia factor, it's always going to be relegated to a handful of niche applications. Meanwhile, I don't see Kodak getting back into consumer photography, much as I love photography, since it's a low margin and increasingly niche business. Also, they sold off their medical imaging division in 2007.
I miss those Kodak CCDs.
