As the quality of digital improves, film will continue to disappear. Despite the fanatics, film will become harder to get, a special order item at some point, and at a rising price. The same will be true of film processing.
The transition from film to digital will be necessary at some point for every serious photographer, it is just a matter of when.

I wouldn't be so sure about that. There may very well be problems with digital photography that we haven't discovered yet as is often the case with new technologies.
A couple I already know about:
* Good luck if you run down your batteries and there is nowhere nearby to recharge. In the first 10 years of my career, I quite often was away from any electric outlet for a couple weeks at a time. With my film cameras, no problem. One does not use any battery and another uses it only for the meter. I know enough about exposure that even if I lose that battery (which lasts for months anyway) I can still get usable images.
* Digital is not that cheap compared to film if you factor in everything. The three film bodies I still have, two are over 25 years old and my Leica was my Dad's before I "stole" it from him so it's 35-40 years old. Do you really think you're ever going to use a 25 yo digital body? It might still work but are you going to want to use an 8-10 mp body when everybody else is using a 20 mp? Then you have to factor in the cost of bigger and bigger computers to handle the bigger and bigger files that your images are becoming; software upgrades (some people here don't even have any software except free stuff that doesn't seem to do much); more and more harddrives (and whatever over media) to store all your photos and make multiple back-ups because you can't really trust your photos to just one; etc, etc.
* Then there's the historical conservation question. I have a collection of about 300 glass negatives that I am getting ready to use in a project. Those were found by a friend of mine in the attic of a rental vacation home by the sea. Who knows how long they had been sitting there and 90% of them are in perfect condition. I also have a collection of about 500 glass stereo slides from WWI that also came from an attic where they probably sat for many years. 75% of them are in perfect condition and there's a museum waiting for me to die so they can get their hands on them

How much do you think would be left of harddrives, CDs or DVDs after so many years of improper storage? If some people can't afford proper software to PP their photos, what's the likelihood their are backing up their collection properly?
You could say that the pros do and that is all that matter. Unfortunately, that's wrong. A whole lot of historically valuable photos today were shot by amateurs. Both of my collections were shot by amateurs. My glass negatives were shot by the village priest and the stereo slides were shot by a lowly soldier. I'm also sitting on a 200 lbs trunk full of photos (both prints and negatives) that I inherited from one of my uncle a couple years back. Family photos. Ok, so what? Well, my greatgrandfather was a designer/engineer/test pilot/etc in the automobile/vehicle industry. My dad and his brother (the uncle) have already contributed a bunch of "family photos" to two books. There are already two more in the works and I haven't gone through half of what's in the trunk. And those were all amateurs' photos.
How much of that kind of stuff are we going to lose because of digital? Have you seen the movie "Letters from Iwo Jima"? The movie was based on letters written by soldiers who were there and, when it came out, I remember reading an article about the fact that the likelihood of such a movie being done about the present Iraq war is very unlikely since soldiers don't write anymore... they e-mail.
* and last, there is this little accident that happened to a friend of mine that I can't help but think about sometimes when I look at my DSLR. He fell off a boat with his cameras. We reacted quickly and both photos and cameras survived. Do you want to try that with a digital body? Considering what happened to my wife's cellphone when she dropped it in a toilet for about 10 seconds, I don't.
You talked about TV studio technology so I'll tell you about audio recording technology. All the studios that I am still in touch with have kept their 2" tape recorders and most of them use them on a regular basis.
Things to think about...
