Would Ilford want to take on making other B&W films which would likely only take sales from their own existing and similar product range? I've not seen any rush by other companies to pick up Pan-X, Plus-X, and all the other discontinued Kodak products.
If they would gain the tri-x customers along their existing customers I don't think they would complain. I hope Kodak will survive or find a good buyer for their film division. We'll see. There is always still Fuji, Ilford, Fome, Shanghai and so on. I think for us the magic word will be adaptation for the coming years.
