I know this may be a difficult question to answer but...

How much longer will Kodak and Fuji make 4x5 color film, both negative and transparency? At least five years? Less? Any good, solid facts available to answer this question? I'm thinking of dumping my 4x5 gear and strictly shoot larger formats in b&w and use (gasp!) digital for any color I need to shoot. Kind of thinking out loud.

Thanks,

Thom
