Sad to say this is yet another reason why modern day journalism has taken a crap. Emphasis on disposable approach. I tend to disagree strongly with your statement that the image isn't really needed much beyond that. Some of the most prolific photographs ever made were made by photojournalists on the job.
If Joe Sixpack flips his Pickup truck into the ditch, the local stringers news photos of that event, probably mean little or nothing after the article is published on page 11 of the local rag. There are some news events, where the photos become immortal, like the photos of famous person being killed, but that's what maybe a few dozen a year, world wide.
Where digital imaging will really prove itself failing in the next 25 years, is as a recorder of personal history. An example of a recording of history, on the personal level is a faded, stained, battered print of my Grandfather, who died in WW-I, nearly 50 years before I was born, this is the only clue, I have as to what he looked like. I know that silver based chemical prints will last 100 years, because that photo of my Grandfather, was taken in 1912, so it's 97 years old now, pretty good chance it will still be viewable in 3 years. I wonder about the claims of ink based digital prints lasting 100 years, considering that I have colour negatives from 1977 that have faded considerably since then. Different dies I know, but they probably didn't think colour negatives would fade that much, that quickly either. The B&W negatives from then, are like brand new.
