I'm not worried about 120 film being discontinued. I think there will still be a market for it in the future. You can easily buy oil paints or charcoal sticks today, so perhaps 120 film will be sold in art stores in the future? Perhaps bundled with developer and fixer in nice gift packages? -- What I'm more worried about, are for instance problems like air travel with films. Some years ago one would just take a camera, could buy film everywhere and could also get it developed at the destination. How do you do it today? (But then it also would be virtually impossible to take your oil paints and stuff like turpentine on the plane today... crazy!)
