To be honest, I'm retired, and happy if Ilford don't retire any film products.
A new film product from Ilford will be truly exciting. I can't remember any recent new film products, other than format size adjustments for marketing.
Preferable 'extreme' or specialist niche: extreme IR; or extreme slow grain IR film like Pan IR F+ ; not just medium grain FP4+ used as a substrate. Or even extreme speed (Ilford Delta 3200 sensitised to 850nm would be). Please don't make it another FP4+ with extended red sensitivity to another 100nm. That would be the definition of Kodak: an anti-climax. Unless it was in sheet film ....hmmm maybe then it would be exciting
