Yea I think tri-x will be around as long as Kodak is, and probably even after in some form, as it's one of the most loved films that has ever been produced. Just this arista premium version won't be, a logical move by Kodak, as it's half the price of kodaks official rolls, but a terrible thing for people and programs that depend on these lower prices. My film and darkroom budget hasn't increased for the classes I teach in the last 3 years, while these costs have gone up 30%. When the time comes I guess the students will learn on something like foma (bah!).
